traveling comfort of guarantee.

In the present embodiment, roll adjustment baseplate also can be positioned at left side, and makes left half cushion can adjust position, and right half cushion is fixed on head backing plate.Realize and allow roll adjustment baseplate on seat backing plate, adjust position, can also have other embodiment, such as setting-in magnet on roll adjustment baseplate, the material that makes head backing plate is can be by the material of attraction, as steel, can regulate like this position of roll adjustment baseplate.Also can directly fix right half cushion or roll adjustment baseplate with thread gluing in addition, can adjust width equally like this.

Because cushion is soft, face forces up rear cushion and has the tendency of outside movement, if the narrow cushion of spacing between depression can skew, the present embodiment is further improved this, as shown in Figure 18 and Figure 19, on head backing plate 6, be provided with left half cushion rib 611 in the left side of left half cushion 81, left side wall and the left half cushion rib 611 of left half cushion 81 are fitted, on roll adjustment baseplate 9, be provided with right half cushion rib 911 on the right side of right half cushion 82, right side wall and the right half cushion rib 911 of right half cushion 82 are fitted, rib can prevent that cushion from skewing, can reduce like this width of cushion and the width of head backing plate.

As shown in Figure 20-27, the junction of chest support and lifting cover also has one embodiment more easily.

As Figure 20, shown in 21 and 22, chest support is divided into (43) two supports under (42).Lifting cover 212 and chest lower bracket are hinged, lifting has put two and has determined gusset plate 2114, determining has a rotating shaft hole and several latch holes 21141 on gusset plate, inserts in the different latch hole 21141 of determining gusset plate and can change the connecting bridge of chest backing plate and the angle on ground or make chest support in using or receiving state with latch 436 and 440;

Axle 21133 is through the axle hole 437 on axle hole and the chest lower bracket 43 determined on gusset plate.Chest lower bracket 43 is determined the middle rotation of gusset plate 2114 at two.

There is individual spring tongue hole 435 chest lower bracket 43 lower ends, have two latches in left and right in hole, are respectively 436 and 440, and on it, all cover has Compress Spring 441 and 444; Also have a lever, its one end is the slide block 439 longitudinally rotating, and the other end is button 431, and centre is passed by axle 433, and under button, surface cover has Compress Spring 434; Also have bracing frame 443 and lid 432.

The downward wall of bracing frame 443 and lid 432 forms a supporting walls with hexagonal hole, carries left right pin afterbody 438 and 442 and limit them and move in hole.But cover has Compress Spring afterbody larger than spring on latch, spring can push away latch afterbody and moving in hexagonal hole like this.

Latch afterbody 438 and 442 is larger than latch head, also has inclined-plane, has a slide block 439 vertically moving in the middle of two latch afterbodys, and slide block both sides have inclined-plane and latch afterbody inclined-plane to coincide, and slide block both sides leniently narrow with inclined-plane;

Spring tongue chamber 435 also has a lid 432, in the middle of it, has individual hole, has individual button 431 in hole, presses this button and can drive the right and left latch 436 and 440 to move horizontally;

In the time vertically moving slide block 439 in stabilized conditions, its the widest part is clipped in the middle of two latch afterbodys 438 and 442, spring 441 and 444 compressions on latch 436 and 440, the hole that latch 440 and 436 passes on chest support enters in described latch hole 21141 of determining gusset plate 2114, and chest support is fixed and can not rotates around axle 21133 like this; When pressing the button 431, below button, there is a spring 434 compressed, button driving vertically moves slide block 439 and moves up, the part being clipped between two latch afterbodys 438 and 442 narrows, spring 441 and 444 expansions on latch, latch 440 and 436 is pushed away inward, exit the latch hole 21141 of determining gusset plate, chest support can rotate around axle 21133 like this; When chest support forwards correct position to, release button 431, Compress Spring 434 below it is expanded, button is up pushed up, drive vertically moves slide block 439 and declines, and makes a forcible entry in the middle of two latch afterbodys 438 and 442, because its entering part is more and more wider just latch 436 and 440 holes toward extrapolated chest lower bracket, enter determine on gusset plate 2114 latch hole 21141, chest support is fixed.

Above-mentioned button 431 with vertically move slide block 439 and connect as lever, it has axle hole, centre to have an axle 433 to pass in the middle of connecting, button 431 and slide block 439 are respectively in the both sides of axle 433;

434 spring-compresseds in the time that button 431 is pressed below it, vertically move slide block 439 and upwards rotate, and the part being clipped between two latches 436 and 440 narrows; Spring expansion below in the time of release button 431, drives longitudinal sliding block 439 to rotate, and is clipped in two parts between latch and broadens.

The downward wall in two, rear portion of lid 432 can limit lever button must not sway; Thicker restriction longitudinal sliding block 439 in the middle of bracing frame 443 bottoms is moved further downwards.

The benefit of this mechanism is to change the angle on chest support and ground without inserting latch with hand, thus the part latch that latch is chest support can not lose, very graceful.

As shown in Figure 28 and Figure 29, seat backing plate also has a kind of folding embodiment.

Bottom manifold 21 outer walls have screw thread, and upper cover has folding seat backing plate, and seat backing plate has with the junction of bottom manifold 21 screw thread mating.The height of seat backing plate can regulate around bottom manifold 21 by turning seat backing plate.Seat backing plate is placed under seat while use, heads on seat bottom lower surface.

Seat backing plate is divided into left and right two handles; Left handle is made up of the handle 164 of left handle pedestal 166 and left handle; Right handle is by the handle 162 of right handle, right handle pedestal 163, slider button 161, the compositions such as lid 160 and spring 167.Described every handles has a lunette, the screw thread on lunette and bottom manifold 21 thread surface couplings;

Described left and right two handles form a ring or ring jaggy altogether, encase bottom manifold 21;

Two handles are hinged near package seat cushion plate stem one end;

At the other end away from bottom manifold 21 bars, left handle side has the pillar 165 of one and half flechette-type tips, and the corresponding side surface of right handle has a hole, has " L " shape groove behind hole, has individual slider button 161 in one side of groove;

161 1 of described slider buttons are half flechette-type tip, and a spring 167 is enclosed within on the pillar of other end, also have a lid 160 with hole to cover " L " shape groove, and this lid is fixed on right handle; Slider button 161 protrudes upward a projection, and this projection is through the hole on lid;

Half flechette-type tip 165 of left handle side can be through the hole of above-mentioned right handle side, squeeze above-mentioned slider button 161 and enter " L " shape groove completely, thereby then slider button 161 is subject to spring 167 compressing to pin left handle toward the shank moving forward and withstand half flechette-type tip 165 of handle side;

Pin the projection of slider button 161 toward pusher, then pulling outward with the left handle of half flechette-type tip 165, can release;

Above-mentioned every handles is divided into pedestal (163,166) and rear end handle (162,164); Pedestal is motionless, and rear end handle is connected with pedestal by an axle (169,170), and can be around axially upper rotation; When rear end handle keeps flat, there is part pressing pedestal.

The benefit that this seat backing plate is implemented is collapsible, when user receives, only need be declined, and does not need that it does not remove.

Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skill in the art make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
