Abstract

The device has cross-members (2) integrated to a floor pan of a motor vehicle via a base plate (6). The cross-members are deformed, in the form of an arch, towards the front by the movement of a load during an impact undergone by the vehicle. Each cross-member has a front face with local deformations, and a rear face (22) with local deformations (28). The deformations of both the faces are oriented to the interior of the cross-members and are in contact inside each cross-member. Fixation holes (68) are placed at the rear of the plate to integrate the plate to the floor pan. An independent claim is also included for a motor vehicle comprising a floor pan load retaining device.
