described in this document apply to the structures and the complete seats. The front seat structure Supplier must provide support and properties as required to meet the seat complete requirements. It is essential that the front seat structure supplier and the seat complete/JIT supplier work together to resolve issues and provide a complete seat system that meets all the requirements detailed in this SOR.GM SOR APPENDIX C Page vi of vi Original Issue Date: 06Dec01CG1804 Revision Date: 07Dec06 Document Uncontrolled When PrintedGLOBAL SUBSYSTEM TECHNICAL SPECIFICATION 1 INTRODUCTIONThis section is to briefly describe the document and its subject and program name.1.1 Scope of Document Define the intent of document and identify the subsystem and vehicle to which it applies. This document establishes the technical specifications for seat complete subsystems. This specific document establishes the technical specification for GMX XXX seat systems. This document will be used both for the front seat structure and for the seats complete (JIT) for all seating rows SORs. The sections that are not directly specific to the seat structure but which are used for the seat-complete specifications are included as reference to the structure supplier.The seat structure subsystems include cushion frame and back frame, adjusters, adjuster actuators, child seat anchors, recliners, seat control cables, belt restraints attachments, risers, floor attachments, all necessary wiring pigtails to connect to the seat wiring harness, and all fasteners needed to assemble all of the preceding. The structure supplier is also responsible for all related component testing and structure system testing. These structure subsystems must accommodate all seat-complete content as described in Appendix B (such as belt restraints, belt pre-tensioners, SIAB, seat position sensors, suppression system, heat systems, cooling/ventilation systems, foam locating strategy, trim finishing and attachment strategy, plastic closeout attachments, etc.) and must fit within the seat STOs (Seat Trimmed Outline). In addition, these structure subsystems must assist in meeting all of the integration requirements of the seat-complete subsystems such as finished appearance, craftsmanship, comfort targets, packaging, and full functionality. The seat complete (JIT) supplier will be responsible for all the foam, trim, plastic closeouts, handles, knobs, switches, memory modules (directed buy), SIAB, belt restraints, seat position sensor switch, suppression system, heat systems, cooling/ventilation systems, the seat wiring harness, and all fasteners needed to assemble all of the preceding. The JIT supplier is also responsible for the final assembly process to create a complete seat ready for delivery to the GM assembly plant. In some programs, the suspension system, lumbar system, head restraint armature, head restraint post guide assemblies, and armrest armature may be the responsibility of either the structure or the JIT supplier.As further clarification, the seat complete (JIT) supplier is responsible for seat complete testing that is non-structural in nature (i.e., sliding entry, jounce & squirm, heat & cooling, suppression, trim, plastics, leather, foam) and the structure supplier is responsible for all structural testing to ensure a well designed and integrated system. The seat complete/JIT supplier is responsible for all testing on rear seats.It is essential that the seat structure supplier and the seat complete (JIT) supplier work together to resolve issues and provide a complete seat system, which meets all the requirements detailed in this SSTS. In this specification the terms “seats and seat system” are defined as encompassing all of the seats in their entirety, together with any belt restraints, in-seat SIR, occupant sensing, and/or seat position sensing. Seat belts, Airbags, sensors and other directed buy components are covered in separate specifications.Key Definitions:shallA binding provision; a must should Denotes preferences when specifying alternatives or desired conformance with objectives, standards, etc. Which if not met must be documented and disclosed by the supplier and approved by the appropriate GM AuthorityTBDTo be determined - Refers to items that are specific to the seat under consideration, and must be established by the GM engineering authority.The supplier shall interpret those item(s) having leading blanks marked by the responsible GM engineering authority, and those items where there are no leading blanks whatsoever, as applicable and binding on all seat systems and portions thereof procured under this specification, unless explicitly indicated otherwise.
