Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1 and 2, an integrated long stroke headrest according to a preferred embodiment of the present invention includes a seat cushion 1, and a seatback 2 rotatable with respect to the seat cushion 1. The headrest framework 3 is arranged on the chair back 2, the movable headrest 4 is installed on the headrest framework 3, the two guide rail grooves 5 are formed in the chair back 2 along the length direction of the chair back 2, the two guide rail grooves 5 penetrate through the front surface of the chair back 2, the headrest framework 3 can slide relative to the guide rail grooves 5, the movable headrest 4 slides on the headrest framework 3 along with the sliding of the headrest framework 3, and the displacement stroke of the movable headrest 4 is close to 20 cm.

The electric control equipment for driving the headrest framework 3 to move is arranged in the chair back 2, the electric control equipment for driving the headrest framework 3 to move is arranged, and the movable headrest 4 can move through electric energy, so that the chair is labor-saving and convenient to use.

The position of the movable headrest 4 can be electrically displaced along the length of the chair back 2, which has the advantages that:

1. is suitable for the requirements of the crowds with different heights, and the crowds with different heights can accurately pillow the head at the movable headrest 4. To the individual, because lie, sit the difference of gesture, the head can take place the skew for activity headrest 4's position, through the removal of automatically controlled activity headrest 4, also can be more accurate with everyone's headrest in activity headrest 4 departments, satisfy individual lie, the position of sitting attitude requirement, use the flexibility more to increase, simultaneously, do not need driver's people eyes to observe the headrest position, need not the manual fixed headrest of driver, can not disperse driver's attention, the driving safety of being convenient for.

2. The headrest position is electrically adjusted, so that the whole structure is labor-saving and convenient.

As shown in fig. 3, the electric control device includes a motor 6, a lead screw 7, a lifting support plate 8, a slide rod 9, and a guide tube 10.

The guide tubes 10 are provided with two, and are arranged on the chair back 2, two sliding rods 9 can respectively slide along the axis of one guide tube 10, and the guide tube 10 is arranged on the outer side of the sliding rod 9. The pillow frame and the lifting support plate 8 are respectively arranged at the end parts of two ends of the sliding rod 9, the screw rod 7 is in threaded connection with the lifting support plate 8, the motor 6 provides power for the rotation of the screw rod 7, and the motor 6 is transversely arranged and is perpendicular to the screw rod 7. After the screw rod 7 rotates, the screw rod 7 drives the lifting supporting plate 8, the sliding rod 9 and the movable headrest 4 to move simultaneously, and the guide pipe 10 guides the sliding rod 9 in a sliding manner, so that the movable headrest 4 is displaced.
