Base structure for seat of motor vehicle, has suspension layer comprising safety section for rigidifying frame rear crossmember when crossmember is bent forward by tractive efforts on anchoring loop during shock subjected by motor vehicle

摘要

The structure (10) has two side flanges (11, 12) extending along longitudinal direction between front parts (13, 14) and rear parts (15, 16). A suspension layer (20) extends between the two side flanges and supports cushioning of a seat, where the suspension layer has a rigid twine netting (21) integrated with a frame rear crossmember (18). The suspension layer comprises a safety section for rigidifying a frame rear crossmember (25) when the crossmember (25) is bent forward by tractive efforts on an anchoring loop (30) during shock subjected by a motor vehicle.
