Improvement of adjustment structure of vehicle headrest

The present invention relates to an improvement of the adjustment structure of a headrest for a vehicle, in particular to a cushioning elasticity and a rotational damping of the pivotal joint, so that the side panel has a clamping force and a pressing force at an adjustment angle.

According to the ergonomic concept, the headrest structure of the vehicle is designed to not only adjust the front and rear inclination of the headrest bracket, but also adjust the angle of the side panel pivoted on both sides of the headrest bracket to allow the user's head. The neck and neck are safe and comfortable.

However, when the side panel pivoted by the headrest bracket is adjusted in angle, the pivotal joint between the headrest bracket and the side panel has the following problems: (1). The longitudinal force is generated based on the side panel, so that the pivot joint is subjected to the upper and lower sides. Impact, it is not easy to clamp and cause side panel vibration. (2). The lateral force is generated based on the side plates, so that the pivot joints are subjected to left and right impacts, and the side plates cannot be loosened.

Therefore, the headrest for the car is used, so that there are still some imperfections, there is still room for improvement.

The main purpose of this creation is to provide an improved adjustment structure for the headrest for a vehicle, which enhances the cushioning elasticity of the pivot joint to solve the problem of the side panel vibration caused by the prior art, and thus the pivot The effect of the clamping force on the side plates is improved.

Another object of the present invention is to provide an improved adjustment structure of a headrest for a vehicle, which strengthens the rotational damping of the pivot joint to solve the problem that the front panel cannot be loosened in the prior art, and thus the pivot joint The side plate has an enhanced effect on the pressing force.

The technical means adopted by the present invention comprises: a headrest bracket having a set of symmetrical pivot joints on the front side; and two side panels having a top joint and a lower joint at the side, between the upper joint and the lower joint The pivot joint of the headrest bracket is disposed; and the two pivots are combined with the upper joint, the middle joint and the lower joint, and the bolt has a bolt, a washer, an elastic washer and a nut, and the bolt The front end of the bolt is fixed and the rear end of the bolt is exposed, and the washer and the elastic washer are sequentially inserted into the bolt. Further, the rear end of the bolt is provided with a partial thread and is locked to the partial thread by the nut; thereby, the lower joint, the washer and the elastic washer abut each other, the elastic washer A cushioning elastic clamping force is provided when the upper pivot joint and the lower pivot joint rotate, so that the side panel can stably adjust the angle of the headrest bracket via the pivot.

According to the predecessor feature, a damping element may be further disposed between the central joint and the upper or lower pivot joint, so as to have a damping contact surface between the central joint and the upper or lower pivot joint.

According to the pre-existing feature, the creation further comprises a supporting portion which is coupled to the front of the headrest bracket and located between the pivots, and has a set of splints, a shackle rod and a screw, and the set of clips The sleeve is sleeved on the shank, and the screw is inserted through the clamping plate to the headrest bracket.

According to the foregoing features, the present invention further includes a head body that is coupled to the back of the headrest bracket.

According to the foregoing feature, the creation further comprises two ㄩ-shaped rods which are laterally coupled to the bottom side of the headrest bracket.

With the technical feature of the above, the adjustment structure of the headrest for the vehicle is improved, and the pivot joints with the upper joint, the middle joint and the lower joint form a pivot joint, and the elastic joint is not only at the pivot joint The gasket strengthens the cushioning elasticity, and also strengthens the rotational damping by the damping unit, so that the pivoting joint has the effect of clamping force and pressing force on the side plate.

First, referring to FIG. 1 to FIG. 5, a preferred embodiment of the adjustment structure of the headrest for the present invention includes: a headrest bracket 10 having a set of symmetric center joints 11 at the front, in this embodiment The present invention further includes a head main body 60 coupled to the rear of the headrest bracket 10 and two ㄩ-shaped rods 70 connected laterally to the bottom side of the headrest bracket 10.

The two side panels 20 are provided with an upper pivot joint 21 and a lower pivot joint 22 on the side thereof. The pivot joint 11 of the headrest bracket 10 is inserted between the upper pivot joint 21 and the lower pivot joint 22.

The two pivots 30 are combined with the upper joint 21, the central joint 11 and the lower joint 22, and have a bolt 31, a washer 32, a spring washer 33 and a nut 34. The bolt 31 is extended. The upper joint 21 and the lower joint 22 are fixed to the front end of the bolt 31, and the rear end of the bolt 31 is fixed, and the washer 32 and the elastic washer 33 are sequentially inserted. The rear end of the bolt 31 is further provided with a partial thread 311 at the rear end of the bolt 31 and is locked to the partial thread 311 by the nut 34. Thus, the lower pivot joint 22 and the washer pad The sheet 32 and the elastic washers 33 abut each other, and the elastic washer 33 can provide a cushioning elastic clamping force when the upper pivot joint 21 and the lower pivot joint 22 rotate, so that the side panel 20 can be in the headrest via the pivot shaft 30. The bracket 10 is stably adjusted in angle.

The present invention further includes a support portion 50 coupled to the front of the headrest bracket 10 and located between the pivots 30. The utility model is composed of a set of clamping plates 51, a ㄇ-shaped rod 52 and a screw 53. The clamping plate 51 is formed. The sleeve is sleeved on the ㄇ-shaped rod 52, and the screw 53 is inserted through the clamping plate 51 to the headrest bracket 10, and is inserted into the vehicle seat by the ㄇ-shaped rod 52, so that the headrest bracket is 10 fixed, however, the pillow body B is used to cover the adjustment structure of the vehicle headrest.

As shown in FIG. 4 to FIG. 5 , a damping element 40 may be further disposed between the central joint 11 and the upper pivot joint 21 or the lower pivot joint 22 , so that the central joint 11 and the upper pivot joint 21 or The lower pivot joint 22 has a damping contact surface 41. In the embodiment, the damping element 40 comprises an elastic gasket, a plastic gasket, a rubber gasket, a silicone gasket, a nylon gasket and the like.

Therefore, the pivot 30 is combined with the upper pivot joint 21, the middle joint 11 and the lower joint 22 to form a pivotal joint. When the side panel 20 is adjusted in angle, longitudinal and lateral forces are generated on the pivot joint. By the cushioning elasticity of the elastic washer 33 and the rotational damping of the damping unit 40, the pivoting portion has a clamping force and a pressing force on the side plate 20, and the side panel 20 is not easily vibrated and loosened.

In summary, the structure revealed by this creation is unprecedented, and it can achieve the improvement of efficacy, and it can be used for industrial utilization. It fully complies with the new patent requirements, and invites the bureau to grant patents to encourage innovation. There is no sense of morality.

However, the drawings and descriptions disclosed above are only preferred embodiments of the present invention, and modifications or equivalent changes made by those skilled in the art in accordance with the spirit of the present invention should still be included in the scope of the patent application.
