The slide rail that is used for seat
Technical field
The utility model relates to the slide rail of installing on the automobile on the seat.
Background technology
The floor that the slide rail of seat is common and the car body of vehicle is interior is connected; adopt double sided slider bar, four point location modes, but the structure of this type and unsatisfactory; locking, the nonsynchronous problem of release appear in regular meeting with respect to body movement the time, and also very high to the requirement of installing.
Summary of the invention
The utility model provides a kind of slide rail that is used for seat, to solve the problem that locking, release are asynchronous, installation requirement is high that present double sided slider bar exists.The technical scheme that the utility model is taked is: longitudinal rail is captiveed joint with crossbeam, right leg assembly is captiveed joint with this crossbeam, left side leg assembly is captiveed joint with this crossbeam, right rolling wheel support is captiveed joint with right leg assembly, the left wheel support is captiveed joint with left leg assembly, guiding trestle device and longitudinal rail flexibly connect, this guiding trestle apparatus structure is, fixed support right piston shoes is respectively captiveed joint with left piston shoes, hollow shaft is captiveed joint with fixed support, roller and hollow shaft are rotationally connected, roller, right piston shoes and left piston shoes and longitudinal rail sliding block joint, the backing pin support is captiveed joint with fixed support, backing pin and backing pin support sliding block joint, and pin one is captiveed joint with fixed support with pin two; The brace panel two ends are fixed with longitudinal rail and crossbeam respectively.
During installation, guiding trestle device and vehicle body are fixed, seat is connected with moving part, and can move forward and backward along fixed part.
Advantage of the present utility model is novel structure, and a kind of three-point-type seat slide rail is provided, and has solved double sided slider bar locking, the nonsynchronous problem of release, can reduce installation requirement, and does not have locking, the nonsynchronous problem of release.
