Problems solved by technology

For example, a car seat headrest with a button that can move up and down and forward and backward is disclosed in the publication number CN102700442. Its X-direction and Z-direction unlocking methods and sliding forms are relatively complicated, and the force loss during the unlocking process will be severe and the unlocking force is also difficult to control.
In addition, the shells of the existing four-way headrests are connected in the form of front and rear or upper and lower buckles and screwing, so that the form of the buckle fit makes the strength poor, the assembly links are many, and the reliability and efficiency are not high.
In addition, the headrest insert rod of the existing four-way headrest is limited in assembly, so that the matching structure is limited and can only be made into an open type, the sliding fit method is single, and there is a problem of fit clearance.
If the headrest inserting rod is divided into two inserting rods and there is a headrest twisting problem

Embodiment Construction

[0066] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0067] see figure 1 and figure 2 , the new four-way headrest shown in the figure includes a headrest shell 100, a U-shaped headrest rod 200, a Z-direction sliding fixed sleeve 300, an X-direction sliding fixed sleeve 400, a tongue 500, and an unlocking wire 600, unlocking button 700, unlocking mechanism bracket 800, X-direction sliding guide 900 and other parts.

[0068] The headrest shell 100 is a plastic part, which is prepared by blow molding or hot melting. The bottom of the headrest shell 100 is open, so that the U-shaped headrest rod 200, the Z-direction sliding fixed sleeve seat 300, the X-direction sliding fixed sleeve seat 400, the snap tongue 500, the unlocking wire 600, the unlocking button 700, the unlocking mechanism bracket 800, Parts such as the X-direction slide guide 900 are fitted into the headrest housing 100 . In additi...

Abstract

The invention discloses a novel four-direction headrest. The four-direction headrest comprises a headrest housing, a U-shaped headrest rod, a Z-directional sliding fixing sleeve seat, an unlocking mechanism bracket, a clamping latch, a clamping latch return spring, an X-directional sliding fixing sleeve seat, an X-directional sliding guiding part, unlocking steel wires and an unlocking button; the Z-directional sliding fixing sleeve seat, the unlocking mechanism bracket and the U-shaped headrest rod are locked and unlocked through the unlocking wires; the clamping latch is driven by the unlocking steel wires to move to lock and unlock the clamping latch and the X-directional sliding guide part. According to the novel four-directional headrest, unlocking and locking mechanisms are simple, efficient and controllable.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to a novel four-way headrest. Background technique [0002] At present, the four-way (X-direction and Z-direction) head restraints are mainly used in the front seats of cars. For example, a car seat headrest with a button that can move up and down and forward and backward is disclosed in the publication number CN102700442. Its X-direction and Z-direction unlocking methods and sliding forms are relatively complicated, and the force loss during the unlocking process will be severe and the unlocking force is also difficult to control. In addition, the shells of the existing four-way headrests are connected in the form of front and back or up and down buckles and screwing, so that the form of the buckle fit makes the strength poor, the assembly links are many, and the reliability and efficiency are not high. Furthermore, the headrest insertion rod of the existing four-way headrest is lim...
