Quick Answer
A seat occupancy sensor mat is a pressure-sensitive mat or pad used inside an automotive seat to detect whether a person is sitting on the seat. In an OEM seat project, the mat is usually placed under the seat foam, inside the cushion stack, below upholstery, or inside a custom seat module, depending on the seat structure. We design the mat shape, sensing zone, activation condition, cable route, connector, and moisture-resistant structure around the customer’s seat drawing. The confirmed circuit design determines the final signal behavior.
JASPER Electronics は、標準のスペアパーツではなくカスタムのカーシート占有センサー マットを必要とする OEM バイヤー、自動車シート エンジニア、調達チーム、シート システム開発者をサポートしています。当社は、新しいシート プログラム、サンプルの検証、製品の供給に重点を置いています。
OEM シート プログラムの製品概要
JASPER Electronics は、自動車シート システム、乗客検出プロジェクト、シートベルト リマインダー システム、商用車シート、およびカスタム車両シート向けのカスタム シート占有センサー マット ソリューションを製造しています。お客様のシート図面、クッション部、センシング要件、コネクタ仕様を基に作業を行います。
The product can also be described by buyers as a car seat occupancy sensor mat, seat occupancy mat, passenger seat occupancy mat, seat occupancy sensor pad, car seat occupancy sensor pad, seat sensor pad, or car seat sensor pad. These terms stay together because OEM sourcing teams may use different wording for the same seat detection function.
| Buyer term | What it usually means in an OEM project | JASPER design response |
|---|---|---|
| Seat occupancy sensor mat | Mat-style sensor for detecting occupied seat condition | Define mat outline, sensing area, activation condition, cable route, and connector |
| Car seat occupancy sensor mat | Seat mat used in vehicle seat systems | Match the seat foam, cushion stack, and assembly path |
| Passenger seat occupancy mat | Mat used in passenger seat presence detection | Tune the sensing zone around the passenger seating surface |
| Seat occupancy sensor pad | Pad-style sensor with a compact sensing area | Define pad size, exit tail, connector, and mounting method |
| Car seat sensor pad | General sourcing term for seat pressure or occupancy detection | Clarify whether the project needs contact detection, pressure detection, or another confirmed circuit design |
センサーマットの仕組み
シート占有センサー マットは、難しいパッケージの中で簡単な仕事をします。クッションを通る荷重の経路を監視します。乗客が座ると、フォームの圧縮により、定義された感知領域に圧力または接触が生じます。実際のシートは決して平らではないため、マットの輪郭、感知窓、ケーブル出口はクッションの設計に従う必要があります。
私たちは検出動作をカタログ番号ではなくエンジニアリング目標として扱います。サンプル生産の前に、JASPER はシート構造、予想される着座状態、回路要件、コネクタ図面、ケーブルルート、および検証計画をレビューします。このレビューにより、プロジェクトにコンパクトなパッド、より長いマット、特別な出口テール、または別のカスタム ジオメトリが必要かどうかが決まります。
公開技術参考文献である Google Patents US20060192417A1 には、マット フィルム間に感圧センサー素子が配置された座席占有検出マットが記載されています。私たちはその特許を背景用語としてのみ使用します。 JASPER 独自の材料スタックと回路構造は、OEM 図面、プロトタイプのレビュー、およびサンプル検証計画に基づいたものでなければなりません。
着座センサーマットの設置場所
シート占有センサーマットは、シートの目に見える外側ではなく、シートアセンブリの内側に取り付けられています。正確な位置は、クッションの厚さ、フォームの圧縮挙動、室内装飾品の構造、シートトリムプロセス、ケーブルの出口方向、および車両プログラムで必要な検出ゾーンによって異なります。
| Installation position | Typical use case | Design notes for engineers |
|---|---|---|
| Under seat foam | Projects where the mat must sit below the main cushion layer | Check foam compression path, mat thickness allowance, and cable exit direction |
| Inside cushion | Projects that need the sensor closer to the occupant load path | Confirm the cushion stack, assembly process, and protection from folding stress |
| Below upholstery | Projects where the mat needs a shallower seating position | Confirm trim pressure, upholstery tension, and long-term contact condition |
| Custom seat module | Special seats, commercial vehicle seats, or module-based cushion systems | Provide module drawing, available space, connector location, and mounting interface |
初期の RFQ レビューでは、シート断面図または物理サンプルを希望します。どちらも利用できない場合は、上面から見たマットの輪郭、予想される検知ゾーン、ケーブルの出口方向、およびコネクタの仕様から始めることができます。
カスタム設計オプション
JASPER Electronics は、OEM シート設計に合わせてシート占有センサー マットをカスタマイズできます。最も一般的なカスタマイズ領域は、マットの形状、感知領域、起動条件、ケーブル長、コネクタ、ケーブル出口方向、表面保護、およびラベル要件です。
| Custom item | What we need from the OEM team | Output from JASPER |
|---|---|---|
| Mat shape | Seat top-view drawing, cushion boundary, forbidden zones | Custom outline matched to the seat package |
| Sensing area | Target occupant detection zone and non-detection zones | Defined sensing window or sensing pattern |
| Trigger force / activation pressure | Expected occupied-seat condition and validation method | Project-specific activation design after engineering review |
| Cable length | Cable route from mat to controller or harness | Cable length and exit direction matched to assembly path |
| Connector | Connector drawing, mating connector, pin requirement | Connector option selected or built to customer specification |
| Moisture-resistant structure | Exposure condition, cleaning process, humidity risk | Protection approach defined after material and structure confirmation |
| OEM label / drawing support | Label format, part number rule, drawing template | Drawing, label, and sample documentation for approval |
| Sample validation | Test seat, sample quantity, pilot schedule | Prototype samples for fit check and detection review |
No two seat cushions behave the same under load. A sports seat, a rear bench, a bus seat, and a specialty module can all need different mat boundaries and cable exits. For that reason, JASPER sets the final parameter list from the engineering file, not from a fixed catalogue table.
Material and Structure Parameters to Confirm
Seat sensor materials are selected after the seat environment is known. We ask for the cushion stack, installation position, exposure condition, and validation requirement before naming a material layer. This avoids an early PET, FPC, adhesive, or coating claim that may not fit the final seat package.
| Parameter group | What should be defined | Why it matters |
|---|---|---|
| Flexible base structure | Film or flexible carrier type after engineering confirmation | Controls fit, bending behavior, and cushion integration |
| Sensing/contact layer | Circuit structure based on the required detection behavior | Controls the sensing response and signal logic |
| Spacer or adhesive structure | Layer spacing, bonding area, and assembly method | Controls repeatability and resistance to assembly stress |
| Protection layer | Surface protection based on moisture and abrasion exposure | Controls handling during seat assembly and service life target |
| Cable interface | Cable length, exit angle, strain relief, and routing | Reduces stress during cushion installation and seat movement |
| Connector interface | Connector type, mating part, pinout, and locking method | Supports integration with the OEM harness or seat module |
| Label and traceability | Part number, revision, batch code, and customer label format | Supports sample approval and production control |
If the OEM team has confirmed material names, electrical output values, temperature targets, life-cycle targets, or certification requirements, we can carry those items into the drawing package. If they are still open, we mark them as items to verify during sample review. Guessing does not help a seat engineer.
用途
Seat Belt Reminder Systems
A seat occupancy sensor mat can support a seat belt reminder system by detecting whether a seat is occupied. The seat system can then combine the occupied-seat condition with buckle status, warning logic, and the vehicle program’s control requirements. We provide the mat as a custom sensing component; the final system logic belongs to the customer’s vehicle electronics design.
Passenger Detection
A passenger seat occupancy mat is used to detect presence on a passenger seat. In OEM programs, the sensing area, activation condition, and installation position must be matched to the seat cushion design. We help the seat engineering team define the mat outline and cable route before sample tooling.
Automotive Seat Pressure Sensing
Some sourcing teams call this product a car seat pressure sensor pad because the mat responds to pressure or contact inside the cushion. We clarify the required detection behavior during RFQ review, then align the mat construction with the seat foam, cushion stack, and harness position.
Custom Vehicle Seats
Commercial vehicle seats, bus seats, specialty seating modules, and project-specific automotive seats often need a non-standard seat sensor pad. JASPER can develop that layout from a seat drawing, detection target, cable route, connector requirement, and sample schedule.
技術メモ for RFQ
For a faster quote, send the seat drawing first. Then add the installation position, expected occupant detection threshold, connector requirement, cable route, exposure condition, and sample quantity. A cushion sample helps when the foam compression path is not clear from CAD.
Our RFQ review has 6 checkpoints: seat structure, sensing zone, activation condition, circuit requirement, cable route, and connector interface. Miss one checkpoint and the first sample may fit the drawing but fail the seat. We try to prevent that before prototype sampling.
| RFQ item | Preferred input | If not available |
|---|---|---|
| Seat drawing | 2D or 3D seat cushion drawing | Top-view sketch with dimensions |
| Installation position | Under foam, inside cushion, below upholstery, or module location | Photo mark-up from the seat sample |
| Detection threshold | Target occupied-seat condition | Engineering discussion with validation sample |
| Cable routing | Exit side, length, bend points, and strain relief area | Preliminary cable route proposal |
| Connector | Connector drawing and mating part | Connector family or harness photo |
| Exposure condition | Moisture, cleaning, heat, abrasion, or assembly pressure | Risk list from the seat team |
| Production target | Sample quantity, pilot lot, annual estimate | Initial sample-only request |
製造 and Validation Approach
JASPER Electronics builds seat occupancy sensor mat projects through drawing review, prototype sampling, fit check, detection review, and production preparation. We do not publish one universal test value here because the useful validation method must match the customer’s seat structure and vehicle program.
The working path is practical. Confirm the seat package. Define the mat geometry. Build samples. Test the sensor in the real seat. Revise the drawing if needed, then prepare production files. The seat is the test environment that matters.
| Stage | What happens | Customer output needed |
|---|---|---|
| 1. RFQ review | We review drawings, installation position, and signal requirement | Seat drawing, detection target, connector data |
| 2. Design proposal | We define mat outline, sensing area, cable exit, and connector approach | Approval of layout and critical dimensions |
| 3. Prototype sample | We make samples for seat fit and detection review | Sample test feedback and change notes |
| 4. Engineering revision | We adjust shape, sensing area, cable route, or connector details | Updated seat data if the cushion changes |
| 5. Production preparation | We lock drawing, label, inspection points, and packaging notes | Approved drawing and purchasing forecast |
FAQ
What is a seat occupancy sensor mat?
A seat occupancy sensor mat is a pressure-sensitive mat or pad placed inside a seat to detect whether an occupant is present. In automotive seats, it is commonly used for passenger detection, seat belt reminder systems, and custom seat pressure sensing projects.
Where is a seat occupancy sensor mat installed?
A seat occupancy sensor mat is usually installed under seat foam, inside the cushion, below upholstery, or inside a custom seat module. The correct position depends on the seat structure, cushion compression, sensing zone, cable routing, and assembly process.
Can JASPER customize the sensor mat shape and trigger force?
Yes. JASPER can customize the sensor mat shape, sensing area, activation condition, cable length, connector, cable exit direction, and moisture-resistant structure according to the OEM seat design. Final trigger force or activation pressure is confirmed through drawing review and sample validation.
Is a seat occupancy sensor mat the same as a seat occupancy sensor pad?
In many OEM sourcing conversations, seat occupancy sensor mat and seat occupancy sensor pad refer to a similar mat-style component used for seat presence detection. We clarify the required shape, sensing zone, installation position, and circuit behavior during RFQ review.
Can the mat support seat belt reminder systems?
Yes. A custom seat occupancy mat can support a seat belt reminder system by detecting occupied-seat condition. The vehicle system can then combine that condition with buckle status and warning logic designed by the OEM or seat system developer.
What information should we send for a custom seat sensor pad quote?
Send the seat drawing, installation position, expected detection condition, connector requirement, cable route, environmental exposure, sample quantity, and production target. If drawings are not ready, a marked photo or seat cushion sample can start the JASPER engineering review.
