Abstract

The utility model discloses a four direction head pillow, which comprises a foaming surface cover, a skeleton and a downward cover plate. The skeleton comprises a clip spring comprising an integrated clip portion and a penetration portion, wherein, a screw hole is arranged on the clip portion. A plastic member is a platform structure with an installation hole penetrated. The clip portion of the clip spring is clipped with the platform. A whorl connection member penetrates through the screw hole and the installation hole to fix the clip spring on the plastic member. A head pillow inserting pole has a rotary portion which penetrates through the penetration portion of the clip spring. The clip spring is clipped on the rotary portion of the head pillow inserting pole and the plastic member, and fastened by the screw connection member to fix on the plastic member. Therefore, the head pillow inserting pole can rotate around the penetration portion of the clip spring that rotates around the plastic member. The rotating torque can be regulated by fastening torque. Such that, the head pillow realizes infinite variable regulation of front and back angle, is suitable for requirements of different sizes of the passengers, thereby improving the comfort and safety of automobile riding.

Description

The four-way headrest

Technical field

The utility model relates to a kind of four-way headrest, specifically, relate to the headrest adjustable height and can before and after the car seat headrest of angle of step-less adjustment headrest.

Background technology

The headrest of automotive seat is for improving a kind of device that vehicle ride comfort and safety are provided with.The chair headrest of manned vehicle is adjustable mostly now, can regulate the height and the front and rear angles up and down of headrest.Regulating headrest can be so that headrest be fitted more with occupant's nape shape, and the good more safety of fitting is high more.Regulate mostly being the step type adjusting before and after the headrest of existing automotive seat, i.e. adjusting is divided into fixing several grades.Because passenger's stature is different, the front and rear angles of headrest is regulated and can only be fixed on several seats, can make a part of passenger can't reach the requirement of comfortable ride-on vehicles, because the applying degree of passenger and headrest is not good, also can cause safety issue simultaneously.

The utility model content

The purpose of this utility model is, a kind of four-way headrest is provided, and can only be fixed on several seats to overcome existing front and rear angles of headrest adjusting, thereby cause the not good technical matters of vehicle ride comfort and safety.

In order to achieve the above object, the technical solution of the utility model is as follows:

A kind of four-way headrest comprises the foaming face cover that fits together, skeleton and lower cover; Described skeleton comprises: jump ring comprises the clamping part of one and wears portion that clamping part is provided with screw; Plastic Parts has a platform structure, is equipped with mounting hole on this platform; The clamping part of jump ring and described platform clamping are passed described screw and mounting hole is fixed on jump ring on the Plastic Parts by threaded connector; And the headrest inserted link, have a rotating part; This rotating part is located in wearing in the portion of jump ring.

Adopt above-mentioned four-way headrest, jump ring be stuck in the headrest inserted link rotating part on after, be stuck on the Plastic Parts again, by threaded connector jump ring is tightened and to be fixed on the Plastic Parts, the headrest inserted link just can rotate around the jump ring portion of wearing, just relatively around the Plastic Parts rotation, moment of rotation can be regulated by screw-down torque.Like this, headrest just can be realized the step-less adjustment of front and rear angles, adapts to different stature passengers' demand, thereby improves traveling comfort and safety that automobile is taken.

The portion of wearing of described jump ring is the circular arc with opening, and described headrest inserted link is a round bar.

The clamping part of described jump ring is from two of the opening part one extension of the portion of wearing parallel platy structures.

Distance between the described two parallel platy structures is less than the diameter of inserted link rotating part, the rotating part of inserted link wear jump ring wear portion after, can be from wherein not skidding off.

The center of the rotating part of described inserted link is located in wearing in the portion of jump ring, and the external diameter size and the internal diameter size that wears portion of the center of rotating part are complementary.

The rotating part two ends of described headrest inserted link one respectively are extended with a body of rod.

Described lower cover is provided with the strip shape hole, the body of rod of ccontaining headrest inserted link.Headrest flip angle scope is controlled by the length in the hole on the lower cover.

The specific embodiment

According to Fig. 1 to Fig. 7, provide preferred embodiment of the present utility model, and described in detail below, enable to understand better function of the present utility model, characteristics.

Fig. 1 is the assembly drowing of the utility model four-way headrest, and Fig. 2 is the STRUCTURE DECOMPOSITION scheme drawing of the utility model four-way headrest.As shown in the figure, four-way headrest of the present utility model comprises foaming face cover 1, skeleton 2 and lower cover 3 three parts, and the three fits together.

Fig. 3 is the STRUCTURE DECOMPOSITION scheme drawing of the headrest skeleton in the four-way headrest features, and Fig. 4 is the assembly drowing of the headrest skeleton among Fig. 3.As shown in the figure, skeleton 2 is by holding screw 4, headrest inserted link 5, and jump ring 6 and Plastic Parts 7 are formed.Headrest inserted link 5 is a round bar, has a rotating part 51 and the rotating part 51 two ends body of rod 52 of one extension respectively.

Fig. 6 is the constructional drawing of the jump ring among Fig. 3.As shown in the figure, jump ring 6 comprises the clamping part 62,63 that is wholely set and wears portion 64 that clamping part 62,63 is provided with screw 61.The portion that wears 64 of jump ring 6 is for having the circular arc of opening 65.The two parallel platy structures 62,63 that opening 65 place's one of the portion that wears 64 of jump ring 6 are extended are the clamping part of jump ring 6.

Fig. 5 be among Fig. 4 the headrest skeleton biopsy cavity marker devices after enlarged diagram.As we can see from the figure, Plastic Parts 7 has a platform structure 71, is equipped with mounting hole 72 on this platform 71.Jump ring 6 is stuck on the center of symmetry of headrest inserted link 5, the midway location place of rotating part 51 of inserted link 5 promptly rests the head on, be stuck in again on the platform 71 of Plastic Parts 7, by holding screw 4 jump ring 6 is tightened and to be fixed on the Plastic Parts 7, like this, headrest inserted link 5 just can wear the internal diameter rotation of portion 64 around jump ring 6, and just relatively around Plastic Parts 7 rotations, moment of rotation can be regulated by screw-down torque.Distance among Fig. 6 between the two parallel platy structures 62,63, just the height of opening 65 is less than the diameter of inserted link rotating part 51.Jump ring 6 has elasticity, after the rotating part 51 of inserted link 5 wears the portion that wears 64 of jump ring 6, and can be from wherein not skidding off.The internal diameter of the portion that wears 64 of jump ring 6 is at rotating part 51 external diameters of free state less than headrest inserted link 5, and after holding screw 4 was tightened, jump ring 6 blocked headrest inserted link 5, thereby provides the headrest rotation required suitable moment.

Fig. 7 is the constructional drawing of the lower cover among Fig. 2.Headrest flip angle scope is controlled by the opening length of the elongated hole on the lower cover 3 31.

Consult Fig. 1 once more, after skeleton assembles, again foaming face is overlapped 1 skeleton 2 and be assembled together, at last lower cover 3 is loaded onto, just be assembled into a four-way headrest assembly.

Above-described, be preferred embodiment of the present utility model only, be not in order to limiting scope of the present utility model, the foregoing description of the present utility model can also be made various variations.Be that every simple, equivalence of doing according to the claims and the description of the utility model application changes and modification, all fall into the claim protection domain of the utility model patent.
