Car crash active safety headrest device with force release mechanism

Abstract

The invention discloses a car crash active safety headrest device with a force release mechanism. The car crash active safety headrest device comprises a seat backrest and a headset framework above the seat backrest, wherein supporting blocking plates are symmetrically arranged on side plates at the two sides of the seat backrest; jacks are formed in the supporting blocking plates; two ends of a U-shaped trigger rod which is horizontally arranged in the middle of the seat backrest are movably inserted into the jacks; return springs are respectively arranged at the two ends of the U-shaped trigger rod; the other ends of the return springs are connected with a backrest side plate; a linkage plate which upwards extends is hinged to the middle of the U-shaped trigger rod; a headrest bracket is fixedly connected at the upper end of the linkage plate; the headrest bracket is horizontally placed on a tube rack on the upper part of the seat backrest; guide sleeves are arranged on the headrest bracket in a spaced manner; the connecting rod of the headrest framework is fixedly inserted into the guide sleeves; a damping hinge is connected in the headrest bracket between the two guide sleeves; a rotary end of the damping hinge backwards extends to a position above the tube rack. The car crash active safety headrest device has the advantages of being simple in structure, light, safe and stable and low in production maintenance cost.

Description

technical field [0001] The invention relates to an automobile seat, in particular to an automobile collision active safety head restraint device with a force releasing mechanism. Background technique [0002] Currently, active safety headrests installed on car seats are gradually becoming popular in the field of automobile manufacturing as a standard configuration. When the vehicle encounters a rear-end collision or emergency braking, the active headrest can promptly and effectively support the head moving backwards after the driver maintains a correct riding posture, significantly reducing the impact on the neck caused by the acceleration at the moment of the collision or emergency braking. The shear force protects the occupant's cervical spine and reduces the damage to the occupant's cervical spine caused by rear-end collisions or emergency braking. However, the development cost of the current active headrest is relatively high. Once triggered, it needs to be replaced...

AI Technical Summary

Problems solved by technology

However, the development cost of the current active headrest is relatively high. Once it is triggered, it needs to be replaced again before it can continue to be used, and the maintenance cost is high.
