摘要

A load sensing mounting (14) for mounting a vehicle seat (10) in a motor vehicle comprising a frame member (20) for the vehicle seat; a mounting bracket (22) for securing in the motor vehicle; a bearing bracket (24) on one of the mounting bracket or the frame member and having a guideway (37) extending in a substantially vertical direction; a bolt (28) secured to the other of the mounting bracket or the frame member, the bolt having a shank (32) which extends through an aperture (34) in said one of the mounting bracket or the frame member and into the guideway of the bearing bracket, the aperture having a predetermined clearance in a substantially vertical direction relative to the shank of the bolt; a resilient plate (38) secured to the bearing bracket across the guideway and engaging the shank of the bolt; and a strain sensing element (44) mounted on the resilient plate on the opposed side to the shank of the bolt. Allows determination of a seat occupant's mass for control of an adaptive restraint system associated with the seat.
