Seat and use definition
Define seat structure, trim, foam, support, expected loads, placement, installation, user states, electronics, diagnostics, environment, and legal owner.
Real flexible sensor geometries with system responsibility kept explicit
Seat Occupancy Sensor Mat Manufacturing Case
This anonymized case uses photographs derived from real JASPER seat-sensor samples to explain the path from zone geometry to a repeatable flexible component. It does not claim vehicle approval, occupant-classification accuracy, threshold values, safety compliance, or a named customer result.
- Real sample familyMultiple flexible zone layouts and wired interfaces are documented
- Defined componentZones, traces, tail, cable, connector, outline, and protection are controlled
- Seat-stack dependencyFoam, trim, support, preload, load path, electronics, and algorithm remain visible
- No safety shortcutVehicle release, classification, warning logic, and compliance remain OEM responsibilities
Evidence basisThe images originate from a documented JASPER seat-sensor sample collection. They prove printed flexible geometry and cable-interface scope, not installed seat-system performance.
Case definition
The component can be manufactured consistently only after the seat load path is defined.
A flexible seat sensor does not observe an occupant independently of the foam, trim, suspension, mounting, wiring, electronics, calibration, and decision logic. The manufacturing case therefore separates the printed or switched sensing component from the installed system. JASPER can control geometry, routing, conversion, cable interface, visual and electrical checks, and production records to an OEM specification.
- Map each sensing zone to the seat support and expected load path rather than copying a generic grid.
- Define whether the component output is contact, resistance, force-sensitive response, matrix, or another OEM-controlled interface.
- Correlate production-intent samples in the representative seat stack before setting thresholds or warning logic.
- Keep component inspection limits separate from vehicle-level classification, diagnostics, and safety release.
Four evidence gates from seat stack to controlled sensor component
Each gate identifies what JASPER can control and what requires OEM system validation.
Sensor release data
Release zone geometry, spacing, traces, substrate, contacts, tail, cable, connector, protection, outline, datums, tolerances, and component acceptance methods.
Representative correlation
Build production-intent components and correlate dimensions, electrical behavior, cable interface, installation, empty/loaded distributions, transitions, faults, and recovery in the intended seat stack.
Production control
Maintain materials, active files, process, fixtures, electrical checks, cable assembly, approved samples, records, packaging, deviations, and change notification.
Separate component evidence from seat-system decisions
A good case record states which evidence belongs to JASPER and which remains with the seat, electronics, software, and vehicle owners.
| Evidence layer | Information to define | Primary owner |
|---|---|---|
| Flexible sensor component | Geometry, zone continuity or response, trace, tail, cable, connector, dimensions, appearance, protection and lot records | JASPER within the quoted component scope |
| Seat mechanical stack | Trim, foam, suspension, support, preload, placement, installation variation, occupant and object load paths | Seat/OEM mechanical system owner |
| Electronics and calibration | Excitation, measurement, filtering, thresholds, hysteresis, diagnostics, connectors, network and change rules | OEM electrical/software owner |
| Vehicle behavior and compliance | Classification, warning logic, fault response, misuse, environmental validation, safety case and market requirements | Vehicle legal manufacturer |
System inputs
Inputs needed for a seat sensor manufacturing review
The component cannot be evaluated from an outside shape alone. The seat, electronics, and intended system decision must be visible.
- 01Seat stack drawings, zone locations, load paths, trim, foam, support, placement, and installation method
- 02Sensor output type, zone map, routing, substrate, contacts, tail, cable, connector, and pinout
- 03Electronics, excitation, measurement range, threshold ownership, diagnostics, and fault states
- 04Empty, occupied, transition, object, misuse, environmental, aging, and recovery test conditions
- 05Component dimensions, electrical checks, fixture, sample stages, traceability, protection, and packaging
- 06Prototype and production quantities, records, legal manufacturer, applicable requirements, and change rules
Seat occupancy sensor case questions
Are the sensor images based on real JASPER samples?
Yes. The displayed family derives from real JASPER sample files. The page claims only visible physical manufacturing scope and does not infer vehicle-level performance.
Can JASPER provide the final occupied/unoccupied threshold?
Thresholds require measured distributions from the intended seat stack, electronics, installation, user states, objects, environment, faults, and decision rules. JASPER can supply controlled components and agreed component evidence.
What should a first sample close?
It should confirm fit, placement, routing, cable and connector, basic electrical behavior, installation, repeatability, and the plan for installed seat correlation before production release.
Does a seat sensor mat automatically meet automotive requirements?
No. Applicable requirements, qualification, safety analysis, diagnostics, vehicle integration, documentation, and release are determined by the legal manufacturer and system owners.
