Embodiment Construction
[0028] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0029] Such as Figure 1 ~ Figure 3 As shown, a headrest locking mechanism includes an installation housing 4 , an elastic reset member 3 , an unlock button 2 and two lock blocks 1 . The two locking blocks 1 are installed in the installation housing 4 facing each other, and both can slide along the installation housing 4, that is, the two locking blocks 1 can approach or move away from each other. The elastic restoring parts 3 are respectively connected with the two lock blocks 1 for driving the two lock blocks 1 to approach each other. The unlocking button 2 is slidably mounted on the installation housing 4 and is used to drive the two lock blocks 1 away from each other.
[0030] See figure 2 and image 3 , the end of the lock block 1 far away from the unlock button 2 is provided with a headrest rod through hole 11, and the headrest rod through hole 11 ...

The invention discloses a headrest locking mechanism, which comprises a mounting shell, two locking blocks and an unlocking button. An elastic reset piece is connected between the two locking blocks,and unlocking matching bevels are arranged at the ends, close to the unlocking button, of the locking blocks correspondingly; one end of the unlocking button is located outside the mounting shell, theother end of the unlocking button is inserted into an unlocking matching opening and abuts against the two unlocking matching bevels. The invention discloses an automobile seat, which comprises a seat backrest and a headrest. The headrest locking mechanism is arranged in the seat backrest, a headrest rod of the headrest is inserted into the headrest locking mechanism, and the unlocking button forwards penetrates out of the seat backrest. By adopting the headrest locking mechanism and the automobile seat, the structure is simple, realization is easy, matching is stable, reliability is good, two supporting rods of the headrest rod can be locked simultaneously, the locking effect is good, one-key unlocking operation at the front end of the backrest is adopted, operation is simple and convenient, and the attractiveness and the high-class sense of the automobile seat are improved.
Description
technical field [0001] The invention belongs to the technical field of automobile parts, and in particular relates to a headrest locking mechanism and an automobile seat. Background technique [0002] When a vehicle collides with the rear, the human body will fall backward due to inertia. At this time, the pressure of vehicle acceleration or deceleration is concentrated on the fragile neck and head of the human body, and the headrest acts as a buffer to protect the human head, so , The headrest is one of the important parts of the car seat. Due to the difference in the stature of each occupant, in order to effectively protect the occupants, most of the seat headrests have a lifting adjustment function to better support the occupant's head. For the convenience of the user, most head restraints can usually be raised without unlocking, but can only be lowered when unlocked. [0003] The headrest rod of the seat headrest has two poles, and the existing car seat is usually equi...
