Adjustment device for headrest

Hinge

An electric adjustment device for sofa headrest includes a first fixing member, a second fixing member, and a drive device having an output end that linearly reciprocates. One end of the second fixing member is pivotally connected to the first fixing member, and the drive device is pivotally connected to the first fixing member and arranged flush with the first fixing member. A sliding direction of the output end is perpendicular to a pivotal axis about which the second fixing member is pivotable to the first fixing member. Specifically, the second fixing member is extended downward to form a fixed end for fixing to a backrest support frame. The electric adjustment device is installed in the headrest support frame instead of the backrest support frame, so that other functional parts are installed inside internal space of the backrest support frame which improves the function of the sofa.

An electric push rod includes a drive motor, an outer tube, a threaded rod, a screw nut and a slider block. The outer tube is fixed to the drive motor, the threaded rod and the screw nut are located in the outer tube, the screw nut is in a threaded connection with the threaded rod, the drive motor is connected with the threaded rod to drive the threaded rod, and the slider block is sleeved on the outer tube and supported on the screw nut. When the threaded rod is rotated inversely to actuate the screw nut to move downwards, the slider block will not move downwards or trend to move downwards due to the screw nut fails to fix on the slider block, thus hands or fingers will not be jammed by the headrest even if the hands or fingers are rested beneath the headrest.

A headrest adjusting device includes a hinge, a fixed base and a drive device. The drive device is fixed on the fixed base and has an output end that is capable of sliding upwards or downwards, the hinge comprises a first rod and a second rod which are pivotally connected together, the second rod can be rotated or locked relatively to the first rod, and the first rod is driven by the output end of the drive device to move upwards or downwards. By the headrest adjusting device, the angle and the height of the headrest can be adjusted independently, thereby meeting demands of the users. Additionally, the hinge and the drive device can be adjusted at the same time, to simultaneously adjust the angle and the height of the headrest.

Headrest adjusting device

A rotary support includes a rotating member, a supporting member, an upper wire, a lower wire and a mounting base, the supporting member is held in the mounting base, the rotating member is inserted into the mounting base and rotatable relative to the supporting member, the upper wire is received in the rotating member and provided with an upper connector, the lower wire is received in the supporting member and provided with a lower connector, the upper connector and the lower connector is provided with a conductive recess and a conductive pin that are engaged one another. The upper wire can be freely rotated relative to the lower wire, thus the wires may not be damaged during the rotation of the table, and the rotation may not restricted by the wires. The connectors of the wires may be connected automatically to simplify the installation of the table.
