The invention relates to a bidirectional unlocking mechanism for an automobile seat backrest. The bidirectional unlocking mechanism comprises an angle adjuster mechanism and an unlocking hand wheel, the recliner mechanism comprises a recliner, an unlocking arm, a limiting pin and a transmission gear, the unlocking arm, the limiting pin and the transmission gear are all arranged on the recliner, anunlocking arm pin is arranged at one end of the unlocking arm, and a toothed plate is arranged at the other end of the unlocking arm and meshed with the transmission gear. A rotating shaft sleeve, hand wheel internal teeth and a push plate are arranged in the unlocking hand wheel; when the unlocking hand wheel is rotated clockwise, the pushing plate in the unlocking hand wheel pushes the unlocking arm pin to drive the unlocking arm to rotate clockwise to achieve unlocking of the clockwise angle adjuster. When the unlocking hand wheel is rotated anticlockwise, internal teeth of the hand wheelare meshed with the transmission gear to drive the transmission gear to rotate anticlockwise, the transmission gear drives the unlocking arm to rotate clockwise, and unlocking of the anticlockwise angle adjuster is achieved. Two-way adjustment unlocking of the automobile seat backrest is achieved through the same unlocking hand wheel, the structural design is compact, operation is easy to understand, and misoperation can be avoided.
Description
technical field [0001] The invention relates to an unlocking mechanism for a backrest of a car seat, in particular to a bidirectional unlocking mechanism for a backrest of a car seat, which belongs to the field of seat back adjustment. Background technique [0002] There are multiple ways for the reclining operation of the backrest of the car seat. The backrest of the recliner is mostly used. The existing technology can realize the unlocking of the recliner by adjusting the handle of the recliner, so as to realize the reclining. But the present recliner handle is generally all designed for the occupant of the seat, and its operation mode generally has only one kind: the occupant pulls up the handle, and the backrest is unlocked. With the diversification of car usage scenarios, there is a new requirement for other occupants to unlock the backrest of the front occupant's seat. To meet the convenience of unlocking operations for different people in different positions, the exis...
