Abstract
The present invention relates to the field of seat accessories, which discloses a pillow adjuster. The connection between a body 130 consisting of a first panel shell 101 and a second panel shell 111 of the pillow adjuster is achieved by the matching between the matched hole 1011 of a boss 1051 of a lead screw 105 on the first panel shell and the second panel shell 111 and the boss 1051 of the lead screw 105, is achieved not by an opening matched with the boss 1051 of the lead screw 105 on the first panel shell 101 and the second panel shell 111. The application of the technical proposal ensures the firmer connection between the panel shell and the lead screw 105 and no problem of the prior technology that the pillow adjuster can not be used due to the declutching of the lead screw 105 and the body 130. The pillow adjuster of the implementation example provided by the present invention is more durable with longer service life, compared with the prior pillow adjuster.
Description
Technical field
The present invention relates to the seat part field, relate in particular to a kind of headrest regulator.
Background technology
Headrest regulator generally is installed in the headrest positions of sofa or backrest, is connected to a fixed with headrest, and the user can pass through headrest regulator, adjusts the angle of inclination of the headrest of headrest, thereby obtains comfortable effect in various degree.
Referring to Fig. 1,2, general headrest regulator mainly adopts following structure at present: headrest regulator comprises: body 120, the screw mandrel 105 that is connected with seat with body 120 respectively, have the opening of " protruding " font at an end of body 120, also be provided with a groove in the end of screw mandrel 105, opening on the body 120 match with screw mandrel 105 projections 1051 and link together (among the figure shown in 121), inlay the gear (internal gears that are provided with the interlock of two mutual edge covers in the inside of body 120, external gear) and spring 112, be connected with swivel plate 104 in the side of body 120, this swivel plate 104 is connected with headrest 130, can be by regulating the spring in the body 120, gear and the angle of regulating swivel plate 104, thus the height of headrest 130 regulated.
But, because there is the opening (121) of broad the junction of this body 120 and screw mandrel 105, so it is wide that this headrest regulator can make that in use for some time the opening (121) of body 120 is ground, cause screw mandrel 105 and body 120 to break away from, cause body 120, screw mandrel 105 to connect firm inadequately.
In addition, in the gear manufacturing, the thickness of gear is thick more, and it is high more to process required cost, and uses in headrest regulator, owing to need often to use, gear is thick more, and its holding capacity is big more, and the service life of headrest regulator is long more, and is durable more.But production firm needs to consider in conjunction with manufacturing cost in process of production, be difficult to obtain equilibrium preferably at cost with on service life, general used gear thickness is limited, after using after a while, can cause strength of gear excessively to break, cause headrest regulator normally not use.
