Seat connection and turnover mechanism

Abstract

The invention relates to auto spare parts, in particular to a seat connection and turnover mechanism. The seat connection and turnover mechanism comprises a backrest frame, a seat cushion frame and seat connecting pieces. The seat connecting pieces are arranged on the two sides of the backrest frame and the two sides of the seat cushion frame and are used for enabling the backrest frame and the seat cushion frame to be connected. The backrest frame can rotate relative to the seat connecting pieces and then be folded in the direction of the seat cushion frame. The seat connection and turnover mechanism further comprises locking mechanisms used for limiting rotation of the backrest frame. The locking mechanisms are arranged on the seat connecting pieces on the two sides of a seat respectively, and the backrest frame is provided with an unlocking switch used for unlocking the two locking mechanisms at the same time. According to the seat connection and turnover mechanism, connecting plates are arranged on the two sides of the seat respectively, so the overall strength of the seat is improved; the locking mechanisms on the connecting plates on the two sides can be unlocked through one-hand operation, so the seat connection and turnover mechanism is convenient and quick to operate, and has a flexible operation mode.

Description

technical field [0001] The invention relates to the field of vehicle accessories, in particular to a seat connection turning mechanism. Background technique [0002] The rear seats of minicars and light commercial vehicles are often turned forward when in use to facilitate cargo placement. The flipping method is to flip the backrest of the seat forward 90 degrees to close up with the seat cushion, and then flip the seat forward as a whole. [0003] At present, the mechanism for controlling the forward turning of the seat back is generally the recliner method, and some use the connection plate method. The recliner has a complex structure, many processing steps, and the cost is relatively high, which is about 2-3 times that of the connection plate method; The way of using the connecting plate needs to be unlocked before turning over. In order to facilitate unlocking, generally only one side of the seat is provided with a locking mechanism, resulting in a low overall strength ...

[0003] At present, the mechanism for controlling the forward turning of the seat back is generally the recliner method, and some use the connection plate method. The recliner structure is complex, the processing steps are many, and the cost is relatively high, which is about 2-3 times that of the connection plate method; The way of using the connecting plate needs to be unlocked before turning over. In order to facilitate unlocking, generally only one side of the seat is provided with a locking mechanism, resulting in low overall strength of the seat. There are also locking mechanisms installed on both sides of the seat and can be simultaneously Unlockable, but due to the unreasonable design of the mechanism, the seat is not easy to meet the strength requirements of the law, and the safety is poor; on the other hand, some seats with locking mechanisms on both sides need both hands to unlock when unlocking. Simultaneously apply force to the seat back, cumbersome operation and low efficiency
