Refering to what is shown in Fig. 3, occupant, which is in, takes normal position, and the head of occupant is not exposed to before knocking into the back
It rests the head on but maintains a certain distance, the head of occupant is substantially supported by cervical vertebra, and cervical vertebra is equivalent to the supporting point on head, and
The back of occupant, from cervical vertebra fulcrum down quite a few, also do not come on backrest completely；When moment of knocking into the back, multiply
The body of member by the forward thrust of seat due to being occurred relative to movement backward until back is resisted against seat back completely
On, but often this in a flash occupant head due to be by cervical vertebra support cannot be directly by the forward thrust of seat, in head
Under the action of portion keeps inertia and seat as you were to travel forward, practical upper cervical spine supporting point is used relative to the holding on head
Property position be directed towards Chinese herbaceous peony direction wink shifting, therefore cause head lose support carry out swinging backward rotation along cervical vertebra supporting point,
Cause the injury that swishes a whip of cervical vertebra.This swing rotary is prevented before generation shown in Fig. 4 thus, the measure taken is exactly
Movable pillow is allowed to rotate forward, when movable pillow 10 rotates to terminal location A ' around rotation axis 11, movable pillow is substantially
Through the rotation for preventing head close to head.
When above-mentioned activity pillow 10 reaches terminal location A ', ideally A ' is right up to head position or head is rigid
It rotates.Since head already has rotational kinetic energy, it is desirable that A ', which can have, bears certain impact force from head
Ability, A ' at this moment cannot rotate to opposite direction because of the pressure by head and even return to movable pillow initial position.
The invention proposes following solution thus.
Firstly, realization activity pillow turns to the position A ': refering to what is shown in Fig. 7, triggering link mechanism 40 passes through its inside
Axle sleeve II41 is fixed on backrest, and the sliding bar 42 that can be horizontally slipped is equipped with inside axle sleeve II41 with respect to axle sleeve
II41 is slided.(as shown in Figure 2) is welded and fixed by welding bars and support frame 30 in axle sleeve II41, in this way triggering link mechanism
Can be built in support pillow can also be separately from the outside of support pillow, as long as its function can be played.Movable pillow
Body 10 is hinged by pin shaft I 45, connecting rod 44 and pin shaft II46 with triggering link mechanism.It is being fixed on movable pillow simultaneously
Spherical or cylindrical bayonet lock 14, the sliding on triggering link mechanism corresponding with the bayonet lock 14 are arranged at the bottom of 10 support plate 13
The position that bar 42 contacts is equipped with card slot I 47, and vehicle bayonet lock 14 when not knocking into the back to contact and withstand on the recessed portion of card slot I 47
Position.It is stuck in due to bayonet lock 14 on the concave face of card slot I 47, prevent sliding bar is from horizontally slipping；It is set on sliding bar 42
Compressed spring 43, the spring 43 is in compressive state (energy storage) at this time.When knocking into the back, movable pillow can pass through axis with moment
It covers I 12 to rotate around rotation axis 11, also moment is detached from the bayonet lock 14 on the depressed area card slot I 47 of sliding bar 42 and movable pillow A
Contact releases self-locking state, and spring 43 discharges rapidly energy, pushes 42 moment of sliding bar to slide to tailstock direction, with sliding bar
42 hinged connecting rods 44 drive and movable pillow 10 are accelerated to rotate around rotation axis 11.It is unfettered in order to rotate connecting rod 44
Lever mechanism is calculated with convenient for geometry, its activity space is increased at one end pin shaft II46 of connecting rod 44 thus, that is, is supporting
A sliding slot 15 is opened on plate 13, pin shaft II46 can be free to slide in sliding slot 15.The above realizes movable pillow 10
Around rotation axis 11 acceleration turn to the position A '.
This activity pillow 10 turns to the position A ', is by the movable inertia of pillow 10 itself and the inertia of sliding bar 42
Collective effect under trigger, in addition trigger mechanism 40 acceleration push realize rotation.The initial position shape of movable pillow
State it is to be understood that when movable pillow rotate moving axis be turned back to location A from the position A ' when, the concave face card slot I 47 of sliding bar 42
Gradually CONTACT WITH FRICTION, frictional force reach a timing and block sliding bar 42 with bayonet lock 14, have occurred and self-locking are fixed on movable pillow
Initial position.This return, which is equivalent to, to be had occurred after the activity pillow of knocking into the back has been pivoted into A ', is needed the return that will rest the head on, is needed to use
Spring 43 is compressed to energy storage state and returns to original position by certain strength, and at this moment sliding bar 42 is slided from the front to the back until by card
Firmly.When knocking into the back, the inertia of movable pillow 10 itself be to maintain it is as you were, and due to triggering link mechanism, support pillow
Body 20 and support frame 30 are fixed on seat, will moment forward movement, movable pillow 10 will be with rotation axis 11 together with seat
Two parts moment, forward, lower part was backwards (lower mass is big) on top around the generation inertia rotation of rotation axis 11 up and down on boundary；And axle sleeve
II41 also will equally move forward at this time with support frame 30, and sliding bar 42 is since inertia phase moves backward axle sleeve II41,43 energy of spring
Amount moment obtains initial release.The two comprehensive function the result is that by the contact of bayonet lock 14 and I 47 concave face of card slot of sliding bar
Frictional force overcomes, and terminates self-locking state, triggering rotation, and realization activity pillow 10 turns to the position A '.
Movable pillow 10 turns to the position A ', that is, requires the position A ' that can have and bear certain impact force from head
Ability, the position A ' at this moment cannot rotate to opposite direction because of the pressure by head and even return to the initial of movable pillow
Position.Refering to what is shown in Fig. 8,43 abrupt release energy storage of spring, which pushes, to be slided after the triggering link mechanism triggering that the invention proposes
Lever 42 slides into terminal location to tailstock direction, and sliding bar 42 turns to the position A ' by lever mechanism drive activity pillow simultaneously
It sets.Position at this time, movable pillow 10 and 42 water of pin shaft I 45, the substantially line direction of connecting rod 44 and pin shaft II46 and sliding bar
Square at an acute angle.Head is contacted with the position A ' when due to knocking into the back, and the stress of the position A ' typically horizontally, only rotates
Movable pillow could be rotated back into initial position from the position A ' by the power of 11 direction of rotation of moving axis, but also spring to be overcome to be pressurized
Reaction force, therefore activity pillow will not rotate even because of the pressure by head to opposite direction in the position A ' when knocking into the back
Return to initial position.It should be pointed out that due to pin shaft II46 increase activity space can in sliding slot 15 it is free to slide, make
Relatively small amount swing can be occurred around rotation axis 11 by obtaining the position A ', when by the flexible swing so that the position A ' and head contact
The position on head can preferably be adapted to, moreover it is possible to which buffering preferably protects head with the mutual excess impact in head.
In one embodiment, bayonet lock 14 is replaced with into brake switch 16, brake switch 16 passes through in signal wire and automobile
