Collision buffering device of automobile seat

Abstract

The invention discloses a collision buffering device of an automobile seat. Linear bearings are installed on the two sides of the upper surface of a bottom plate, the two sides of a moving plate are connected to sliding parts of the linear bearings, the two sides of the front of the moving plate are connected with the outer ends of spiral springs respectively, and the inner ends of the spiral springs are connected with the bottom plate. An insertion groove / insertion grooves is / are formed in one side / two sides of the rear of the moving plate, a locking pin / locking pins corresponding to the insertion groove / insertion grooves is / are arranged at the rear of the bottom plate, and a reset spring / reset springs is / are installed on the locking pin / locking pins. The collision buffering device has the advantages that once an automobile is severely collided, an automobile body is extruded inwards, passengers dash forward under the action of inertia to pull safety belts, buckles of the safety belts pull the fixed insertion pins inside the device out of the clamping grooves, and the seat is transformed into a moving state from a fixed state. Under the action of restoring force of the spiral springs, the moving plate drives the seat to move backwards along the linear bearings by a certain distance, the seat and the passengers move synchronously, safety spaces are made in front of the passengers, and therefore it is avoided that due to extrusion, the chests and the legs of the passengers are hurt.

Description

technical field [0001] The invention relates to an automobile seat impact buffer device, in which a fixed seat becomes a rearwardly movable seat when the vehicle is impacted. Such a large amount of impact mitigation strength can make the driver, occupant's chest and legs free from extrusion trauma because the seat becomes a movable seat. Greatly reduce the direct damage of car accidents. Background technique [0002] When the vehicle is hit violently, the front part of the vehicle is sunken into the vehicle under the action of the huge impact force, squeezing the driver's chest and legs, which not only causes disability, but also greatly increases the difficulty of rescue work. Contents of the invention [0003] The object of the present invention is to provide an anti-collision cushioning device for the seat of the driver and passenger of a car with an anti-collision function, so as to solve the problem existing in the prior art that when the vehicle is violently collide...
