Abstract

The invention discloses an automatic collapse unloading device for overload prevention of an automobile seat leg bracket. The automatic collapse unloading device comprises a supporting rod, a sleeve, a supporting plate A, a connecting plate A, a connecting plate C, a bolt nut A, a drive mechanism and a collapse unloading structure. The collapse unloading structure is connected with the sleeve through the connecting plate C. The supporting rod is sleeved with the sleeve in a sliding mode. The sleeve is provided with a slot in sliding fit with a positioning pin, and the positioning pin is matched with the supporting rod. The supporting rod is connected to a cushion framework. The supporting plate A is welded to the sleeve. A supporting plate B is connected with the supporting rod through the connecting plate A and a connecting plate B, and the connecting plate A is connected with the supporting rod. The supporting plate A is movably connected with the supporting plate B through the bolt nut A, and the supporting plate B is connected with a cover assembly. The collapse unloading structure contains a drive rod, a connecting plate D, a hook, a spring, a supporting pin, a bolt nut B, a rivet A and a rivet B, wherein the drive rod is connected with the drive mechanism, the connecting plate D is connected with the drive rod through the rivet B, the hook is connected with the connecting plate D through the rivet A, one end of the spring is hooked to the supporting pin, the other end of the spring is connected to the lower end of the hook, and the supporting pin is connected with the connecting plate C and the connecting plate D through the bolt nut B.

Description

[0001] Technical field: [0002] The invention relates to the technical field of car seat structures, in particular to a device for preventing overload of seat leg rests. [0003] Background technique: [0004] The leg support of the car seat provides comprehensive support for the passenger's legs and achieves the best ride comfort as much as possible. However, in actual applications, passengers may cause leg injuries due to improper use, such as sitting on the leg support. If the load is overloaded, the structure will be damaged in severe cases. [0005] The prior art anti-overload protective device, such as the common automobile crush box, is able to protect other parts when the car collides through the deformation and energy absorption of the stepped or pagoda-shaped crush box . Another example is the safety block of the punch press, which is at the expense of the quick break of the insurance when the punch press is overloaded, so as to block the punching force and protect...
