Description

The slewing arrangement of automotive seat

Technical field

The utility model relates to the layout or the installation of seat on the vehicle, especially a kind of slewing arrangement of automotive seat.

Background technology

Seat on the existing automobile, especially its reaction plate rotation relatively of the seat in the commercial vehicle, use with convenient, after seat turns an angle, be located at slewing arrangement on the seat with seat and reaction plate relative fixed, the constructional feature of this slewing arrangement is: be provided with the tongue piece draw-in groove on reaction plate symmetrically, two tongue pieces are inserted in the cooresponding tongue piece draw-in groove symmetrically, be provided with shackle rod between two tongue pieces, be provided with back-moving spring between tongue piece and the tongue piece draw-in groove, on the center of seat frame, be provided with the strong point, the bar handle that is located on the seat frame side is connected with tongue piece through center support point by steel wire, realization is to the seat actuating, but this slewing arrangement by the steel wire pulling, requirement on machining accuracy strictness to each parts, essential strict symmetrical distribution of tongue piece draw-in groove, essential symmetry of the installation of two tongue pieces and center support point and action simultaneously, otherwise because of the seat unbalance stress shakes or the retractility of centre offset and steel wire self, to cause producing resistance between two tongue pieces and the tongue piece draw-in groove, two tongue pieces lift or the return difficulty, the fault rate height, service life is short.

Summary of the invention

The purpose of this utility model provides that a kind of fault rate is low, the slewing arrangement of long service life, automotive seat simple in structure.

For achieving the above object, the utility model comprises last reaction plate and the lower fixed disk that is connected as a single entity, between last reaction plate and the lower fixed disk rotating disc is installed, be provided with ball between rotating disc and the lower fixed disk, support is installed on the bottom surface of lower fixed disk symmetrically, Carrier for cycle is installed on the rotating disc, its constructional feature is to have uniform groove on the inside circumference of last reaction plate, turning cylinder is installed on Carrier for cycle, be fixed with the tongue piece that can be inserted in the groove on the turning cylinder, tongue piece is provided with locking spring, and the axle head of turning cylinder is provided with the striking gear that makes this rotation.

The quantity of groove is 6-10.

Described striking gear comprises the handle that is installed on the Carrier for cycle side, and handle is connected with turning cylinder by a connecting rod mechanism.

Striking gear can also be a poke rod that is fixed on the turning cylinder.

Principle of work of the present utility model is: when stirring striking gear turning cylinder is rotated, the tongue piece that is packed on the turning cylinder is thrown off with the turning cylinder rotation and with groove, this moment, seat can rotate by the relative fixed dish, when in rotational direction turning to next groove location, tongue piece is sealed with groove under the effect of its locking spring, also can be rotated further behind the suitable position of the next one fixing.

From the above mentioned, the utility model moves two original tongue pieces simultaneously and becomes a tongue piece and rotate, spur two tongue pieces by original steel wire elasticity and become turning cylinder rigidity actuating tongue piece with turning cylinder, can effectively overcome the resistance that produces between tongue piece and the groove, therefore tongue piece lift or return flexible, low, the long service life of fault rate, working stability, and the setting accuracy of tongue piece and groove required to reduce relatively, tooling cost is low.

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1.

The specific embodiment

The slewing arrangement of automotive seat shown in the drawings, comprise the last reaction plate 1 and the lower fixed disk 2 that are connected as a single entity, between last reaction plate 1 and the lower fixed disk 2 rotating disc 3 is installed, be provided with ball 4 between rotating disc 3 and the lower fixed disk 2, support 5 is installed on the bottom surface of lower fixed disk 2 symmetrically, support 5 can be the slide-and-guide frame that slides along the guide rail that is fixed on the vehicle floor, be equipped with and be located at the sealed blocking device of guide rail on the vehicle floor on the slide-and-guide frame, Carrier for cycle 6 is installed on the rotating disc 3, on the inside circumference of last reaction plate 1, have uniform groove 7, the quantity of groove 7 is 6-10, turning cylinder 8 is installed on Carrier for cycle 6, turning cylinder 8 can rotate by winding fulcrum on Carrier for cycle 6 flexibly, be fixed with the tongue piece 9 that can be inserted in the groove 7 on the turning cylinder 8, tongue piece 9 is provided with locking spring 10, locking spring 10 can be installed between tongue piece 9 and the Carrier for cycle 6, also can be installed between tongue piece 9 and the reaction plate, the axle head of turning cylinder 8 is provided with the striking gear 11 that makes this rotation, striking gear 11 comprises the handle that is installed on Carrier for cycle 6 sides, handle is connected with turning cylinder 8 by a connecting rod mechanism, striking gear 11 can also be one to be fixed on the poke rod on the turning cylinder 8, can stir turning cylinder 8 rotations and get final product, striking gear 11 can be installed in any end of turning cylinder 8.
