Abstract

The utility model discloses a manual angle adjusting device of a seat. The manual angle adjusting device comprises an outer toothed plate, a fixing plate, a sheath, a cam, a pair of locking toothed plates and a pair of reset springs. A second section of locking teeth and a third section of locking teeth are added at two ends of a first section of locking teeth on each locking toothed plate respectively outwards. Under the normal unstressed state, the second section of locking teeth and the third section of locking teeth can not be meshed with teeth on an inner gear ring, only when the locking toothed plates are inclined along the stress direction, the second section of locking teeth or the third section of locking teeth can be meshed with the teeth on the inner gear ring gradually. When the angle adjusting device is loaded, no matter the load is forward or backward, the added second section of locking teeth or the third section of locking teeth can be completely meshed with the teeth on the inner gear ring of the outer toothed plate, and the number of meshed teeth of the locking toothed plates and the teeth on the inner gear ring of the outer toothed plate is increased, and therefore under the condition that the number of the locking toothed plates is not increased, the static strength of the angle adjusting device of the seat is improved.

Description

The chair manual recliner
Technical field
The utility model relates to seat reclining apparatus, particularly the chair manual recliner.
Background technology
At present, the seat angle adjustor that is used for vehicle both at home and abroad is installed in the seat of vehicle, and by seat angle adjustor, back of seat can carry out angular adjustment with respect to seat cushion.
Recliner is as vital safety mechanisms, in collision case, thereby recliner should be able to bear and act on seat and be applied to impulsive force on recliner, and large distortion or destruction should not occur.In recent years, the raising along with the seat safety performance requires needs angle regulator for automobile chair can bear higher load.
Implementation of the prior art is just like the disclosed a kind of seat angle adjustor of China Patent No. ZL201010131101.4, referring to Fig. 1 and Fig. 2, it comprises the outer tooth plate (not shown) that is arranged on seat back side and the adapter plate 10 that is arranged on the seat cushion side, and outer tooth plate and adapter plate 10 form mutually and rotate.Be built in the locking tooth plate 20 on adapter plate 10, under the promotion that is built in a pair of wind spring 30 on adapter plate 10, cam 40, control panel 50, reach relatively rotating of restriction adapter plate 10 and outer tooth plate with the tooth engagement on outer tooth plate internally toothed annulus, thus back of seat is fixed on certain angle.
The existing subject matter of this seat angle adjustor is: referring to Fig. 3 and Fig. 4, when recliner in the stand under load situation, no matter forward direction or backward stand under load, due to the locking tooth 21 on locking tooth plate 20 can be not all with outer tooth plate 60 internally toothed annuluss 61 on tooth mesh fully, have part locking tooth 21 be with outer tooth plate 60 internally toothed annuluss 61 on tooth be in half engagement, cause so the whole bearing load of locking tooth 21 on locking tooth plate 20, therefore cause the static strength of seat angle adjustor to descend.
In order to improve the intensity of seat angle adjustor, generally, general recliner so all will cause the significantly rising of cost by increasing by 3～4 jam plate quantity, increasing overall volume and replace the intensity that high strength material improves recliner.
