Problems solved by technology
However, since the end of the headrest rod is made flat, the contact area between the headrest rod and the headrest plug becomes smaller when the headrest is pulled to the highest position, and the headrest will vibrate.
If the headrest rod is lengthened and then the end is changed to a flat shape, the tip of the headrest rod may be touched from the back of the seat when the headrest is at the lowest position due to insufficient space in the seat, resulting in failure to meet safety standards. The extension of the headrest rod can easily lead to the inability to pull out the headrest, let alone pry the glass

The invention discloses a headrest rod, a seat and car with the headrest rod. The headrest rod comprises a rod, a pinch bar and an unlocking knob, wherein a cavity is limited in the rod; an opening communicated with the cavity is formed in the lower end of the rod; the pinch bar is arranged in the cavity by a manner of moving between a retracting position for storing in the cavity and a position in which the opening extends from the cavity; a flat part for being inserted to the lower edge of window glass to pinch and break the window glass is arranged at the lower end of the pinch bar; the unlocking knob is arranged on the rod by the manner of rotating between a locking retracting position in which the pinch bar is locked at the retracting position, a locking extending device in which the pinch bar is located at the extending position, and an unlocking position in which the pinch bar is allowed to move between the retracting position and the extending position. With the adoption of the headrest rod of the embodiment, the function of pinching glass can be realized, the shaking is greatly avoided, thus the safety standard is met, and the convenience is provided to pull out.
Description
technical field [0001] The invention relates to the field of vehicle engineering, in particular to a headrest rod, a seat with the headrest rod and an automobile with the seat. Background technique [0002] In the automobile in the related art, in order to facilitate the personnel in the car to break the window glass to escape when the door cannot be opened, the lower end of the headrest rod is made flat to realize the function of prying the glass. But because the end portion of the headrest rod is made into a flat shape, the contact area between the headrest rod and the headrest plug becomes smaller when the headrest is pulled to the highest position, and the headrest will produce a movement. If the headrest rod is lengthened and then the end is changed into a flat shape, the tip of the headrest rod can be touched from the back of the seat when the headrest is at the lowest position due to insufficient space in the seat, resulting in failure to meet safety standards. The e...
