Locking mechanism for seat after being lifted

Abstract

The invention discloses a locking mechanism for a seat after being lifted. The locking mechanism for the seat after being lifted comprises a locking block, an L-shaped supporting block, an elastic element and an unlocking plate, wherein the locking block is fixed on a seat cushion framework side plate; the L-shaped supporting block is shafted on an upper slide rail in a seat slide rail; the elastic element is released so that the L-shaped supporting block enters a locking state; the unlocking plate is fixed on a lower slide rail in the seat slide rail in an appropriate position; and when the unlocking plate touches the L-shaped supporting block, the L-shaped supporting block is impelled to overcome the resistance of the elastic element to return an unlocking state. According to the locking mechanism for the seat after being lifted, only by using the locking block, the L-shaped supporting block, the elastic element and the unlocking plate, the seat can be supported after being lifted so that feet of passengers in the third row can be prevented; meanwhile, by using the locking block, the L-shaped supporting block, the elastic element and the unlocking plate, the unlocking of the seat in the returning process can also be realized so that the seat is automatically unlocked in the returning process.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to a locking mechanism for a raised seat. Background technique [0002] For SUV and MPV models with three rows of seats, when the third row of passengers enters, it is hoped that the second row of seats will be lifted and moved forward to allow enough space for the third row of passengers to enter and exit. However, in the current process of moving the seat back, the seat is not easy to control, and it is easy to hit the feet of the passengers in the third row. [0003] The current situation of having this functional seat is as follows: [0004] (1) There is no support device, and the seat is kept in a raised state by the power assist system, which is easy to hit the feet of passengers in the third row and the operating force is relatively large; [0005] (2) Increase the lock structure. During the backward process, the seat needs to be unlocked before the seat can be lowered, which...

AI Technical Summary

Problems solved by technology

[0004] (1) There is no support device, and the seat is kept in a raised state by the power assist system, which is easy to hit the feet of passengers in the third row and the operating force is relatively large;

[0005] (2) Increase the lock structure. During the backward process, the seat needs to be unlocked before the seat can be lowered, which is inconvenient to operate and requires a special lock;

[0006] (3) Complex structure, many parts, high cost and high space requirements

The disadvantage is: when returning to the position, it is necessary to operate the shoulder handle 10

There are special requirements for the floor lock 40 and there is no fixed point return function
