Reversible car headrest

Abstract

The invention belongs to the technical field of auto parts, and provides a reversible car headrest. The reversible car headrest comprises a headrest body, a supporting rod, a ratchet wheel, a lock-upassembly and an unlock assembly, wherein an installation space is formed in the headrest body; the upper end of the supporting rod is rotationally connected to the lower end of the headrest; the ratchet wheel is fixedly connected on the supporting rod; the lock-up assembly is rotationally arranged in the headrest, the lower end of the lock-up assembly is movably in clamped connection with the upper end of the ratchet wheel; the unlock assembly is movably inserted into the headrest, and one end of the unlock assembly abut against the upper end of the lock-up assembly; when the unlock assemblymoves, the lock-up assembly can rotate to perform unlocking with the ratchet wheel, and the headrest body can rotate around the joint of the headrest and the supporting rod. Compared with the prior art, the reversible car headrest has the advantages that the structure is simple, the production cost is low, the headrest rotates conveniently, the unlocking process is smooth, the operation hand feeling is good, the connecting relationships and corresponding locations among various structures cannot change easily, the stability is high, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, and in particular relates to a reversible automobile headrest. Background technique [0002] The function of ordinary headrests in passenger cars is generally to provide support for the heads of drivers and passengers. Ordinary rear headrests do not have the function of turning back and forth, and the headrests cannot be turned forward according to the driver's habits and safety needs to provide enough for the driver. vision space. At the same time, the ordinary rear headrest cannot be turned over when the seat is down, so as to provide enough trunk space and reduce the comfort and practicality of the headrest. [0003] In the prior art, the internal structure of some reversible headrests introduced on the market is very complicated, which increases the production cost of the headrest, and is not suitable for use in ordinary passenger cars, and the unlocking structure is relatively comp...

[0002] The function of ordinary headrests in passenger cars is generally to provide support for the heads of drivers and passengers. Ordinary rear headrests do not have the function of turning back and forth, and the headrests cannot be turned forward according to the driver's habits and safety needs to provide enough for the driver. visual space

At the same time, the ordinary rear headrest cannot be turned over when the seat is down, so as to provide enough trunk space and reduce the comfort and practicality of the headrest

[0003] In the prior art, the internal structure of some reversible headrests introduced on the market is very complicated, which increases the production cost of the headrest, and is not suitable for use in ordinary passenger cars, and the unlocking structure is relatively complicated, which is inconvenient to unlock, and the headrest is repeatedly locked. When turning over, the matching structure between the various parts is easily damaged, causing the phenomenon that the headrest cannot be turned over, etc.
