" shape, thereby it can only realize the conversion adjusting between chair and shop by the setting range that enlarges seat angle adjustor.But owing to be subjected to the restriction of described seat support joint plate shape, when the adjusting of seat by recliner was extended into bed and uses, it was poor to exist a height degree between chair back back of the body body and the seat support pedestal, thereby brings uncomfortable sensation to the person of couching.Though have and a kind ofly partly come nationality to overcome the technical scheme of above-mentioned defective by the pedestal of raising seat support, but implement this scheme, must do structural change to whole automotive seat, not only there is certain degree of difficulty in design and change armchair structure, and the materials of whole seat are increased, cause the cost to increase, so technique scheme is actually and is difficult to carry out.

Task of the present utility model is that a kind of structure that need not to change automotive seat will be provided, when seat is extended into the bed use, and the sleeping berth recliner that can not have diff-H between chair back back of the body body and the seat support pedestal, can give comfortable sense for the person of couching.

Task of the present utility model is finished like this, and a kind of sleeping berth recliner comprises a seat support joint plate 4; One anchor shaft 8; On seat joint plate 4; One big tooth plate 10 is on anchor shaft 8; One torsion axis 12 is on big tooth plate 10; One torsion spring 14 is positioned on the big tooth plate 10, and an end is solid mutually with anchor shaft 8, and the other end is solid mutually with torsion axis 12; One little axle 17, little tooth plate 18, on seat joint plate 4, little tooth plate 18 is nibbled with big tooth plate 10 and is joined; One adjusting mechanism on seat joint plate 4, and matches with little tooth plate 18, and the shape of described seat joint plate 4 is sole-shaped.

The utility model since become original chair joint plate 4 shape "

" shape is sole-shaped; after on the chair back of the seat support that seat joint plate 4, big tooth plate 10 is fixed in automotive seat respectively; by the adjusting of adjusting mechanism, when making seat be extended into bed, can there be diff-H between chair back back of the body body and the seat chair body, can makes the person of couching that comfortable sense is arranged.

Below in conjunction with accompanying drawing the utility model is further described below.

Accompanying drawing is the utility model assembling assumption diagram.

One end of seat support joint plate 4 of the present utility model has one and adjusts chamber 32.Integrally moulded shaping when adjusting chamber 32 with 4 shapings of seat support joint plate is provided with an end of anchor shaft 8, little tooth plate 18, torsion spring 14, big tooth plate 10 etc. in the adjustment chamber 32.

Be provided with circular arc boss 6 and raised line 5 in the adjustment of the present utility model chamber 32.Circular arc boss 6, raised line 5 are mold formed on seat support joint plate 4 respectively, circular arc boss 6, raised line 5 are in contact with it by torsion spring 14, little tooth plate 18 respectively, its effect is when

torsion spring

14,18 actions of little tooth plate, can avoid the whole side of torsion spring 14, little tooth plate 18 to rub mutually with base joint plate 4, thereby both can prolong described service life of touching parts mutually, can reduce the action resistance of torsion spring 14, little tooth plate 18 again.

Adjusting mechanism of the present utility model comprises adjusts fork 25, handle 1, spring 26, adjusting the fork 25 adjustment entries 23 that pass on the seat support joint plate 4 by the square toes on it 24 is attached on the seat joint plate 4, handle 1 is solid mutually with square toes 24 by the square hole 2 on it, one end of spring 26 is fixed on to be adjusted on the fork 25, and the other end is fixed on the seat support joint plate 4.Also have a jaw 22 on the adjustment fork 25, the allocating slot 28 on jaw 22 and the little tooth plate 18 matches.Little tooth plate 18 is to pass the little tooth plate hole 29 on it and pass the adjustment hole 3 that is positioned on the seat support joint plate 4 by little axle 17 to be connected on the seat support joint plate 4.Seat support joint plate 4 is solid mutually with the seat support of automobile by the seat support fixed

orifice

30,31 on it.

Both nibble engaging tooth 19 on engaging tooth 20 on the big tooth plate 10 of the present utility model and the little tooth plate 18 mutually and join.Anchor shaft 8 is fixedly arranged on the boss 7 of seat support joint plate 4, and an end of little tooth plate 10 is fixed on the anchor shaft 8 by the axis hole on it 21 cover, the other end of little tooth plate 10 cross screw hole 11 with screw threads so that revolve and the chair back of automotive seat on.Two ends of torsion spring 14 of the present utility model have torsion spring hook 13, fixed head 15 respectively, and torsion spring hook 13 hooks are put on torsion axis 12, and fixed head 15 is embedded on the torsional spring slot 9 on the anchor shaft 8.

Also have one on the adjustment fork 25 of the present utility model and connect spindle nose 27, connect an end of pitman 16 on it, the other end of pitman 16 connects with the utility model that is positioned at the automotive seat opposite side.

When using the utility model, as long as with the hand handle 1 that makes progress, overcome the power of spring 26 and drive square toes 24 by handle 1 and turn an angle, the jaw 22 of adjusting fork 25 is on the allocating slot 28 of little tooth plate 18, thereby drive little tooth plate 18 swing certain distances, make engaging tooth 20 drop out of gears on engaging tooth 19 and the big tooth plate 10 on the little tooth plate 18.At this moment, the application force that only needs back strength etc. by the people to overcome torsion spring 14 makes the Chair back layback, until making the chair back be extended into bed or being in suitable position with respect to seat support.Decontrol handle 1 then, this moment is under the effect of spring 26, the jaw 22 of adjusting fork 25 is repositioned to and supports and the upper end of little tooth plate 18, and the engaging tooth 19 on the little tooth plate 18 fully mesh with engaging tooth 20 on the big tooth plate 10, thereby has guaranteed fixing after the chair back stretching, extension of whole automotive seat.If will be when being extended into the chair back behind the bed and being reset to back of seat, then handle 1 upwards once more at this moment, makes chair back folding become normal seat back by the restoring force of torsion spring 14.
