Seat swivel device for vehicles

Abstract

The invention discloses a seat rotating device for vehicles. The seat rotating device comprises a support plate; an annular lower fixing plate, which forms a first curve part along the edge of a lowerfixing plate; an annular upper fixing plate, which forms a second curve part that is arranged in the first curve part; a rotating plate, which is rotatingly arranged between the lower fixing plate and the upper fixing plate and forms a third curve part that is arranged between the first curve part and the second curve part; and a bearing part, which is arranged between the first curve part and the third curve part and the second curve part and the third curve part. The bearing part comprises a first bearing set, a second bearing set, and an annular bearing accommodating plate. The seat rotating device can stably rotates the rotating plate, at the same time, the dynamic strength and / or static strength of the rotating device are improved; and the reliability of the rotating device is guaranteed.

Description

technical field [0001] The present invention relates to a seat rotating device, in particular, to a seat for a vehicle that can provide convenience for passengers by rotating the seat for setting on the vehicle clockwise or counterclockwise by 180° rotating device. Background technique [0002] Generally, a vehicle seat is mainly arranged to face forward, and adopts a structure capable of moving only in a front-rear direction. [0003] However, some sports utility vehicle (SUV) or recreational vehicle (RV) seats are provided with a seat swivel device to be able to rotate the desired angle in the clockwise or counterclockwise direction, so that the seat can be arranged in the desired position. need status. [0004] However, this seat swivel device is only suitable for a very small number of sports utility vehicles (SUV) or recreational vehicles (RV), and it is only suitable for the rear seat of the vehicle, not for the driver's seat. seat and front passenger seat, therefor...

AI Technical Summary

Problems solved by technology

However, in order to form a space for accommodating the bearings provided between the upper fixed plate and the rotating plate, and the rotating plate and the lower fixing plate when the seat is rotated, it is necessary to make the edges of the upper fixing plate, the lower fixing plate, and the rotating plate smaller. It is complicated to bend, and since the space for accommodating the bearings is open to the outside, foreign substances frequently enter, making it difficult to smoothly operate the rotating plate

[0008] In addition, there are many unnecessary redundant spaces in the housing space for housing the bearings, so the volume of the rotating device will be increased unnecessarily, and if there is a gap formed around the bearing part, the rotating plate will be damaged during operation. As a result, not only the ride comfort is poor, but also there are problems such as being unable to cope with the impact force in the event of a collision, and furthermore, there are various problems such as the rotating plate detaching from the inside of the upper fixing plate and the lower fixing plate.

[0009] Also, in a seat provided with a seat swivel device, load is transferred to the swivel device due to the weight of the seat itself and the weight of the occupant, and when an excessive load is applied to the swivel device, the load is concentrated on the bearing portion, thereby There is also the problem of not being able to rotate the seat smoothly

[0010] Furthermore, in order to rotate the seat, the occupant rotates the seat while lowering the upper body and raising the lever that releases the lock of the rotating plate. During this process, it is necessary to keep raising the lever until the seat is fixed. It is inconvenient for the seat to be fixed to the desired position, and in order to rotate the seat, there is also the inconvenience that the occupant needs to directly grasp the seat and rotate it.
