Abstract
The invention discloses a swing block locking device for a seat angular adjustor, which comprises a swing block, a toothed plate, a fixing plate, a cam and a return spring. The swing block which is meshed with a ratchet of the toothed plate is mounted in the fixing plate with an arc semi-punching boss serving as a center of rotation, the outer periphery of the toothed plate is mounted in a semi-punched inner bore of the fixing plate, a central cone frustum of the cam is in a semi-punched counter bore structure with one end sleeved on a central cone frustum of the fixing plate and the other end fixed in the inner bore of the toothed plate, the return spring is sleeved on the semicircular semi-punched boss of the fixing plate, and one of the return spring is clamped on a hook of the cam. Continuous step adjustment of a seat backrest can be realized by means of the swing block locking device, and a mounting riveting process is stable, reliable and high in efficiency.
Description
Technical field
The present invention relates to a kind of seat angle adjustor, relating in particular to seat angle adjustor internal drive mode is shuttle-type centering block locking device.
Background technology
Seat angle adjustor is mainly used in the backrest adjustment mechanism of automotive seat; Be used for regulating the forward and backward degree of tilt of seat; Make the occupant reach an optimum drive or take angle, and realize the instant locking of back of seat synchronously, guarantee the traveling comfort and the safety of back of seat.
More common in the market recliner core apparatus; Its internal lock locking mechanism two to three slide blocks linear slide in the adapter plate chute that adopt come the unlocking/locking of implement device to end function more; And the locking of slide block lockable mechanism generally need be cooperated by release cam, slide block, locking cam three with release and just can accomplish, and structure is comparatively complicated.Because the tolerance clearance of slide block and adapter plate chute is very little, causes slide block inconvenient operation in fitting process; Because the sliding type recliner is higher to the dependence of chute intensity when bearing external load, often cause the sliding tooth of recliner core members device in addition, thereby cause the inefficacy of chair mechanism function because the chute boss receives shear deformation/fracture.
Summary of the invention
The present invention provides a kind of level that has continuously of back of seat that realizes to regulate, and simple in structure, and construction of stable is easily manufactured, shuttle-type seat angle adjustor centering block locking device that productive costs is lower.
For realizing the foregoing invention purpose, the present invention has adopted following technical scheme:
A kind of pivoting motion type seat recliner centering block locking device comprises centering block, tooth plate, and adapter plate, cam, retracing spring, said centering block is that centre of gration is installed in the adapter plate towards boss partly with circular arc, and is meshed with the tooth plate ratchet; Said tooth plate periphery is assemblied in adapter plate half in endoporus; Said cam center round platform is half towards counter bore structure, and wherein counterbore one end is placed on the round platform of adapter plate center, and the other end is fixed in the tooth plate endoporus; End, said retracing spring center is placed in adapter plate circular arc half on boss, and the other end is stuck in the cam gib head.
Preferably, said centering block is more than two.
Preferably, said retracing spring is more than two.
Preferably, said cam endoporus is interior side.
Beneficial effect of the present invention is, can realize that the level that has continuously of back of seat is regulated, and simple in structure, construction of stable, and easily manufactured, productive costs is lower.
Description of drawings
Fig. 1 is the structural representation of pivoting motion type seat recliner centering block locking device in the present invention's one preferred embodiment.
The specific embodiment
Consult Fig. 1, this pivoting motion type seat recliner centering block locking device comprises centering block 1, tooth plate 2, adapter plate 3, cam 4, retracing spring 5; Centering block 1 is that centre of gration is installed in the adapter plate 3 towards boss partly with circular arc; And be meshed with tooth plate 2 ratchets, tooth plate 2 peripheries are assemblied in adapter plate 3 half in endoporus, and cam 4 center round platforms are half towards counter bore structure; Wherein counterbore one end is placed on the adapter plate 3 center round platforms; The other end is fixed in tooth plate 2 endoporus, and end, retracing spring 5 center is placed in adapter plate 3 circular arcs half on boss, and the other end is stuck in cam 4 gib heads.
Wherein centering block 1 is 2 with retracing spring 5, and wherein the quantity of centering block can be decided according to the performance of recliner core members, and the quantity of centering block 1 is 3 when requirement of strength is very high; The cam endoporus is interior side 7x7, is used for the welding of follow-up seat both sides recliner core members.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all are encompassed within the rights protection scope of the present invention.
