Load-receiving device for car, has mobility elements arranged to ensure and guide captive inertial displacement of support element relative to case when locking element yields under forcing effort whose intensity reaches threshold

摘要

The device (1) has mobility elements (10) blocked by a fusible locking element (11), and arranged to be solicited by a forcing effort (F) whose intensity depends on inertial efforts (I), which are exerted on a support element (3) i.e. roof bar, intended to receive a transport load (4). The mobility elements are arranged to ensure and guide a captive inertial displacement (D) of the support element relative to a case (6) of a vehicle (2) when the locking element yields under the forcing effort whose intensity reaches or exceeds a predetermined threshold.
