Abstract
The invention discloses a pull belt type floor unlocking mechanism installed on a back row seat. A pull ring support is fixedly installed on an upper transverse pipe of a backrest framework. The upper end of an unlocking pull belt penetrates the pull ring support to be connected with a pull ring. The lower end of the unlocking pull belt is hinged to the tail of a T-shaped unlocking handle. The middle position of the head of the T-shaped unlocking handle is hinged to a handle installation support which is fixedly installed in the backrest framework. The upper ends of a left backrest unlocking pull rope and a right backrest unlocking pull rope are connected with the two ends of the head of the T-shaped unlocking handle respectively. The lower ends of the left backrest unlocking pull rope and the right backrest unlocking pull rope are connected with floor locks on the corresponding sides of a backrest. The handle installation support is formed by welding a 7-shaped supporting pipe and a stamped steel plate. The middle portion of the T-shaped unlocking handle is sleeved with a silencing plastic sleeve. By the adoption of the pull belt type floor unlocking mechanism, the lever principle is adopted, much labor is saved for operation, operation can be finished through one hand, the mechanism is more convenient to use, the potential safety hazard that the hand is pinched is avoided, manufacturing cost is reduced, and abnormal sounds are eliminated.
Description
Technical field
The present invention relates to automotive seating art field, be specifically related to a kind of backrest for back seat upset unlocking structure.
