Description
Technical field
The utility model belongs to automobile-used spare and accessory parts manufacturing field, in particular to a kind of automobile collision preventing headrest.
Background technique
Automobile during traveling, occupant with garage into, have biggish inertia, encounter vehicle emergency brake or chase after
When the emergency episodes such as tail, human body is since inertia can collide with adjacent components such as automotive seat and headrests, the violent journey of collision
Degree view inertia size and it is different.In an impact, inertia force is easy to concentrate on the key positions such as the head of human body or neck, is easily multiplied
Member brings biggish wound.And in the manufacturing process of orthodox car headrest, it is often simply soft using cloth material package sponge etc.
Pillow is made in soft fibre product, is fixed on neck and goes out, and such headrest can not provide when automobile speed change suddenly for occupant
Enough cushion effects can not reduce injury of the inertia force to occupant's neck.
And a kind of hollow support is disclosed in the patent application document that number of patent application is " 201510427891.3 "
Bar is mountable on vehicle seat back.Support rod is adjustable, to adjust the height of headrest relative to backrest.Substitute
Capsule is located in headrest and the air bag in hollow headrest support rod intrinsic safety air bag and backrest is arranged in connector
Between system unit.Substitute is placed in hollow headrest by the invention, and controls it by rollover sensor and air bag
Control the work of air bag, which has the following problems: firstly, impact force is excessive when air bag starts, not only without
Method effectively, in time buffers inertia force, is easy to bring occupant's reverse impact power instead, aggravate suffered by occupant's neck
Injury, secondly, the triggering of air bag relies on circuit and its matched control program in the invention, circuit and control program
Reliability is not high, influences vulnerable to external environment and entanglement occurs, and not can guarantee long-term effective stability.
A kind of automotive seat is disclosed in the patent application document that number of patent application is " 201320029368.1 " to knock into the back
Crash-active safety headrest device, it is intended to overcome the problems, such as that the prior art is longer there are the response time.The active head
Pillow device is made of headrest assembly, triggering assembly with 2 bracing wires, and the upper end of 2 bracing wires is fixedly connected with 2 metal blocks, 2 gold
Belong in 2 metal block through-holes on block insertion headrest chamber, No. 3 triggering rack gears and 2 in the lower end and triggering assembly of 2 bracing wires
