Description

Technical Field

[0001] The utility model relates to the field of automobile seats, in particular to a seat structure which facilitates passengers to enter the rear row. Background Art

[0002] In order to highlight individuality, the current passenger car development has become more and more diverse. The proportion of two-door four-seater cars in passenger cars has increased year by year. In order to solve the convenience of rear passengers getting on and off the two-door car model, it is particularly important. However, the existing easy-entry unlocking mechanisms are relatively complex and have many seat components, which increases the difficulty of assembly and greatly reduces the assembly efficiency. In addition, due to the large number of components, they are more easily damaged during later use and have poor reliability. Because they are inside the seat, maintenance and replacement are troublesome and costly.

[0003] The seat slide is composed of a slide core and an outer slide. The outer slide is fixed, and the front and rear ends of the outer slide are respectively fixed to the floor by installing feet. The outer slide and the slide core are locked together by the slide locking mechanism. When the slide needs to be unlocked, pull the unlocking rod in front of the seat slide to unlock it. The slide core can move forward relative to the outer slide under the action of external force.

[0004] In the existing automobile seats, when the passengers in the rear seats need to get in and out, they need to first pull the slide rail unlocking lever to unlock the slide rails of the middle row seats, and then use external force to push the middle row seats forward to free up space for the rear passengers to pass through.

[0005] The main problem with the above structure is that the seat needs to be pushed by external force each time it is unlocked in order to move forward.

[0006] The existing patent 201820647507.X - Automobile seat frame, automobile seat and automobile does not clearly provide technical inspiration for solving the above technical problems.

[0007] In order to improve or solve at least one of the above problems, it is necessary to optimize the design of the existing seat structure. Utility Model Content

[0011] The seat body comprises a seat cushion body, and a backrest is provided on the seat cushion body;

[0012] The seat cushion body is connected to the interior of the vehicle body via a seat track;

[0013] The seat track comprises a slide rail base, on which a slide rail upper track is arranged; the slide rail upper track is connected to a slide rail unlocking handle;

[0014] The backrest is connected to the slide rail unlocking handle through a linkage mechanism;

[0015] The linkage mechanism comprises an unlocking link, and the unlocking link is connected to the slide rail unlocking handle through a slide rail unlocking pull wire;

[0016] A pulling mechanism is provided between the upper sliding rail and the sliding rail base; the pulling mechanism comprises an elastic component for connecting the upper sliding rail and the sliding rail base.

[0017] The elastic component comprises a tension spring; one end of the tension spring is connected to the upper sliding rail, and the other end is connected to the sliding rail base.

[0018] The end of the tension spring is connected to the upper sliding rail or the sliding rail base through a connecting hook.

[0019] The tension spring is connected to the upper sliding rail or the slide rail base via a connecting bracket; the connecting bracket is fixedly connected to the corresponding upper sliding rail or the slide rail base; and each connecting bracket is provided with a hanging through hole.

[0020] The unlocking link is connected to the seat cushion body through a pin shaft; one end of the unlocking link is connected to the backrest, and the other end is connected to the slide rail unlocking pull wire.

[0021] The end of the slide rail unlocking wire is connected to the seat cushion body through a mounting bracket.

[0022] The mounting bracket is provided with a through hole, and the cable of the slide rail unlocking cable passes through the through hole and is connected to the unlocking connecting rod; the cable sleeve of the slide rail unlocking cable is embedded in the mounting bracket.
