Description

Manual regulation headrest

Technical Field

The utility model relates to the technical field of automobile seats, in particular to a manual adjusting headrest.

Background

The automobile headrest is a driving comfort configuration article and a safety protection article. When the vehicle runs into the rear, the human body falls backwards due to inertia, the pressure of acceleration or deceleration of the vehicle is concentrated on the fragile neck and the head of the human body, and the headrest has a buffering effect on the pressure and protects the head of the human body. As the height and sitting posture of each person are different, the height requirement of the automobile headrest is different, and therefore, the automobile headrest with the adjustable height is invented by the technical personnel in the field. However, most of the existing automobile headrests are arranged at the upper ends of seat backs, the headrest rods of the automobile headrests are vertical rods, the automobile headrests can only be adjusted in the vertical direction, and the automobile headrests are difficult to adjust to a comfortable position no matter how the automobile headrests are adjusted. More importantly, due to the fact that the automobile headrest is not well adjusted, the head of a driver and a passenger cannot be effectively supported, and when the automobile collides, the protection effect of the automobile headrest on the head of the driver and the passenger is very limited.

In order to achieve the purpose, the utility model provides a manual adjustment headrest, which comprises a backrest and a headrest arranged at the top end of the backrest, wherein the headrest comprises headrest foam and a headrest rod used for supporting the headrest foam, the headrest rod is n-shaped, the top of the n-shaped headrest rod is bent forwards and downwards, the headrest foam is arranged at the top of the headrest rod, two legs of the headrest rod extend in an arc shape, the extending direction of the two legs is forwards, two through holes are formed in the top end of the backrest corresponding to the two legs, guide bushings matched with the legs are fixedly arranged in the through holes, the two legs are movably arranged in the corresponding guide bushings in a penetrating manner, the top ends of the guide bushings extend out of the through holes, a pressing piece is arranged at the top end of each guide bushing, a clamping block is arranged on each pressing piece, a plurality of clamping grooves are symmetrically arranged on the two legs along the extending direction, and form a clamping structure with any one clamping groove so as to lock the headrest rod, the unlocking of the buckle structure can be realized by controlling the pressing piece, so that the headrest rod can be adjusted to realize the height adjustment of the headrest.

In the scheme, the method comprises the following steps: the pressing piece comprises a button and a spring, the clamping block is fixed on the button, a button cavity matched with the button is formed in the top end of the guide bushing, the button is fixedly connected with the inner wall of the button cavity through the spring, the clamping block is clamped in the clamping groove when the spring is in an initial state, and the clamping block can be withdrawn from the clamping groove when the spring is in a compression state through the control button. The button is pressed through external force, the spring is compressed towards one side far away from the clamping groove, meanwhile, the clamping block is withdrawn from the clamping groove to unlock the headrest rod, the button is continuously pressed until the headrest rod is adjusted to a proper height, a certain clamping groove of the headrest rod corresponds to the clamping block in position at the moment, then, the external force is cancelled, and the clamping block is driven by the restoring force of the spring to be clamped into the corresponding clamping groove to lock the headrest rod; this structural design is simple, and convenient operation just can realize the quick adjustment of headrest height through artifical manual.

In the scheme, the method comprises the following steps: the clamping grooves on each supporting leg are uniformly arranged at intervals. Each clamping groove corresponds to one height adjusting gear, the interval between every two adjacent gears is even, the distance adjusted every time is easier to control, and the adjustment is more convenient.

In the scheme, the method comprises the following steps: the lower end face of the headrest foam is matched with the outer contour of the upper end face of the backrest. It is advantageous to reduce the minimum adjustment height of the headrest as much as possible.

The utility model has the beneficial effects that:

1. because two feet of the headrest rod extend in an arc shape with the extending direction facing forwards, when the height of the headrest foam is adjusted through the headrest rod, the headrest foam can also do inclined motion along with the up-and-down movement of the headrest rod, the headrest foam tilts forwards when the headrest rod moves upwards, and the headrest foam reverses when the headrest rod moves downwards, namely, the headrest can not only realize simple up-and-down adjustment, but also has a certain front-and-back adjusting function, can better support the head of a passenger, improve the comfort level of the passenger, and strengthen the protection effect of the head.

2. The guide bush is arranged in the through hole, and can reduce noise generated when the headrest rod moves, can play a role in guiding the headrest rod, and improves stability of the headrest rod during adjustment.

3. The headrest rod is locked by the clamping block on the pressing piece and the clamping groove on the headrest rod forming a clamping structure, the structure is simple, and the headrest height can be quickly adjusted manually.

4. Be provided with a plurality of draw-in grooves on the stabilizer blade, can realize the many grades of regulations of headrest height, application range is wide, can satisfy different passenger's demand.

Detailed Description

As shown in fig. 1 to 5, a manual adjustment headrest is mainly composed of a backrest 1 and a headrest 2 provided at the top end of the backrest 1. The headrest 2 comprises headrest foam 3 and a headrest rod 4 for supporting the headrest foam 3, the headrest rod 4 is n-shaped, the top of the n-shaped is bent forwards and downwards, and the headrest foam 3 is arranged at the top of the headrest rod 4.

The two legs 401 of the headrest rod 4 extend in an arc shape, and the extending direction is forward. The top of the backrest 1 is provided with two through holes 101 corresponding to the two support legs 401, guide bushings 5 matched with the support legs 401 are fixedly arranged in the through holes 101, and the two support legs 401 movably penetrate through the corresponding guide bushings 5. Through hole 101 is stretched out at the top of guide bush 5, is equipped with pressing member 6 on the top of guide bush 5, is equipped with fixture block 7 on the pressing member 6, and two stabilizer blades 401 are provided with a plurality of draw-in grooves 411 along the extending direction symmetry, thereby fixture block 7 forms buckle structure with arbitrary draw-in groove 411 and locks headrest pole 4, can realize buckle structure's unblock through control pressing member 6 to can adjust headrest pole 4 in order to realize the altitude mixture control of headrest 2.

Preferably, the pressing member 6 includes a button 601 and a spring 602, the latch 7 is fixed on the button 601, the top end of the guide bushing 5 is provided with a button cavity 501 matching with the button 601, and the button 601 is fixedly connected with the inner wall of the button cavity 501 through the spring 602.
