Turnable seat and a vehicle provided with same

Abstract

The invention relates to a turnable seat and a vehicle provided with the same. The turnable seat comprises a seat framework and a seat body, wherein the seat framework is installed on a wall plate, the seat body comprises an L-shaped seat surface and a backrest installed above the seat surface, the backrest is fixed at the top end of the seat framework and closely attached to the wall plate, the seat surface is connected with the seat framework through a turnover mechanism, and the turnover mechanism drives the seat surface to turn over up and down. The turnable seat is simple and compact in structure, stable and reliable in operation and light in weight, the backrest is separated from the seat surface, the backrest does not turn over, the backrest and the wall plate are tightly attached without gaps, and the interior decoration quality of an automobile is improved.

Description

technical field [0001] The invention relates to a seat structure, in particular to a reversible seat, and also to a vehicle equipped with the seat. Background technique [0002] In various passenger vehicles such as subways, various equipment is sometimes arranged in the equipment cabinet under the seat. In order to facilitate the installation and maintenance of the equipment, the seat needs to be designed as a seat whose seat surface can be opened. Existing seats often use multi-link motion mechanisms. For example, Patent No. 201120531471.7 provides a flip-type subway seat, which adopts a one-drive four-link mechanism, uses a gas spring as the driving mechanism, and the four-link mechanism It is composed of seat frame, seat panel, active arm and rotating arm. One end of the active arm and rotating arm is installed on the vertical beam of the seat frame respectively, and the other end of the active arm and rotating arm are respectively connected to the seat of the seat panel...

AI Technical Summary

Problems solved by technology

[0003] In this seat structure, the seat panel is turned over as a whole. Since there is relative movement between the top of the seat panel and the wall panel when turning over, in the closed state, there is a gap between the seat panel and the wall panel, which reduces the quality of the vehicle interior.

At the same time, the seat adopts a four-bar linkage mechanism, which has problems such as many parts, complex structure, heavy weight, and difficult installation. Moreover, the four-bar linkage mechanism is not stable enough during the flipping process, which may easily cause the seat surface and backrest to shake and cause abnormalities.
