Translational energy absorption seat used for protecting neck of passenger during rear-end collision

Abstract

The invention relates to a translational energy absorption seat used for protecting the neck of a passenger during a rear-end collision. The translational energy absorption seat comprises a seat head rest, a seat backrest, a seat cushion, slide rails fixedly connected with the seat cushion, fixed rails fixedly connected with the car floor, locking mechanisms for adjusting the front-back position of the seat, an adjusting handle for adjusting the front-back position of the seat, and translational energy absorption mechanisms mounted below the seat cushion, wherein the translational energy absorption mechanisms are symmetrically arranged on two sides of the seat. As the translational energy absorption mechanisms adopt energy absorption square tubes for extrusion energy absorption, and more stable constraint platform force can be provided. During a rear-end collision of cars, the seat and the passenger can translationally move backwards for certain distance under the action of certain constraint force, so that relative motion of the body and the head of the passenger can be effectively reduced, and the damage to the neck of the passenger can be reduced. The translational energy absorption seat is low in maintenance cost and suitable for multiple conditions, and facilitates wide-range popularization.

Description

technical field [0001] The invention mainly relates to a translational energy-absorbing seat for protecting the neck of an occupant under rear-end collision, and belongs to the technical field of automobile passive safety. Background technique [0002] Rear-end collision accidents are one of the most common types of collisions on the road. Although the fatal injuries to occupants are relatively small, the social costs of whiplash injuries caused by rear-end collision accidents are relatively large. Whiplash injury refers to the injury caused by the whipping movement of the occupant's neck in a rear-end collision. At present, the mechanism of its injury is not clear, but it is generally believed that reducing the relative movement of the occupant's torso and head can reduce whiplash injuries. At the same time, some car manufacturers have produced seats that reduce whiplash injuries based on this understanding. proved to be effective. At present, the existing rear-end collis...

Problems solved by technology

However, these devices are suitable for single working conditions, rough mechanical design, relatively complex structure, high cost, poor motion stability, and large additional mass of the seat, which is not conducive to automobile lightweight, energy saving and environmental protection, and is difficult to promote on a large scale.

Moreover, in the event of a high-speed rear-end collision, the occupant is likely to slip out of the back of the seat, the protection performance is not good, and it is easy to cause other injuries
