Through setting up the support steel wire, can improve the headrest and prevent whipping the performance, both can guarantee the travelling comfort of headrest, can reduce the injury that leads to the fact the passenger in striking in-process again, support steel wire simple structure, occupation space is little, increases EPP or working of plastics cost lower among the compared prior art.

Description

Automobile seat headrest capable of improving whipping resistance

Technical Field

The utility model relates to the technical field of automobile seats, in particular to an automobile seat headrest capable of improving anti-whipping performance.

Background

The automobile seat headrest comprises a headrest and a headrest rod fixedly connected with the headrest, the automobile seat headrest can provide support for the head of a driver and a passenger, the head of the passenger can be protected by absorbing energy in the automobile collision process, and the damage to the head and neck of the passenger caused by collision is reduced. The protection effect is completely dependent on the performance of the automobile seat headrest when the automobile is subjected to rear impact and head whipping, namely the contact stiffness of the automobile seat headrest, and the protection effect is specifically expressed as the rebound speed of the head after impacting the automobile seat headrest.

Because the general foam body has poor stress and energy absorption performance, the energy absorption and buffering functions of the existing L-shaped automobile seat headrest are very limited, and the requirement of the injury index of the head of a dummy is difficult to meet in a collision test. When the impact is encountered, the impact energy cannot be effectively absorbed, so that the possible damage caused by the impact cannot be effectively slowed down, and key parts such as the head and neck of a passenger cannot be protected to the greatest extent in the impact process. Some seat headrests incorporate EPP or plastic members to slow down injuries to the head and neck of the occupant during an impact. The risk of passengers in the back row headrest whisksah experiment process can be effectively reduced by increasing EPP, but the EPP is high in cost, large in occupied space and insufficient in comfort.

Disclosure of Invention

The utility model aims to provide an automobile seat headrest capable of improving anti-whipping performance, and solves the problems of high cost and large occupied space in the existing mode of increasing EPP or plastic parts.

In order to solve the technical problems, the utility model is realized by adopting the following technical scheme:

an automotive seat headrest for improving anti-whipping performance, comprising: the headrest comprises a headrest body 1 and a headrest framework 2 for supporting the headrest body 1, wherein a supporting steel wire 3 is arranged on the headrest framework 2.

Further, the headrest body 1 includes a headrest foam 11, and a skin 12 that is wrapped around the outside of the headrest foam 11.

Further, a surface of the headrest foam 11 contacting the head is closest to the headrest frame 2 by 10 to 15mm.

Further, the headrest framework 2 comprises two support rods 21 with inverted J-shaped structures, and a cross rod 22 is arranged between the two support rods 21.

Further, the support wire 3 is provided on the cross bar 22.

Further, the supporting steel wire 3 has a shape of a Chinese character 'ji'.

Compared with the prior art, the utility model has the beneficial effects that:

according to the automobile seat headrest with the anti-whipping performance, the anti-whipping performance of the headrest can be improved by arranging the supporting steel wires, so that the comfort of the headrest can be ensured, the injury to passengers in the collision process can be reduced, the supporting steel wires are simple in structure and small in occupied space, and compared with the prior art, the cost of increasing EPP or plastic parts is lower.

Drawings

The utility model is further described below with reference to the accompanying drawings:

FIG. 1 is a front view of an automotive seat headrest with improved anti-whipping performance in accordance with the present utility model;

FIG. 2 is a side view of an automotive seat headrest of the present utility model having improved anti-whipping properties;

in the above figures:

1. the headrest comprises a headrest body, headrest foam, a covering, a headrest framework, a supporting rod, a cross rod and supporting steel wires.

Detailed Description

For the purpose of promoting an understanding of the principles and advantages of embodiments of the utility model, reference will now be made in detail to the drawings, in which it is apparent that the embodiments described are some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 2, an automotive seat headrest with improved whipping prevention performance provided in this embodiment includes a headrest body 1, and a headrest framework 2 for supporting the headrest body 1, wherein a supporting steel wire 3 is provided on the headrest framework 2.

The headrest body 1 includes a headrest foam 11, and a skin 12 coated on the outside of the headrest foam 11.

In order to ensure the comfort of the headrest, it is preferable in this embodiment that the surface of the headrest foam 11 contacting the head is spaced apart from the headrest frame 2 by a distance d of 10 to 15mm.

The headrest framework 2 comprises two support rods 21 with inverted J-shaped structures, and a cross rod 22 is arranged between the two support rods 21.

The support steel wire 3 is of a shape like a Chinese character 'ji', the support steel wire 3 is welded and arranged on the cross rod 22, the position and the angle of the support steel wire 3 can be adjusted according to the impact point of the headrest by the head ball in the collision process, and when the impact is encountered, the impact energy can be absorbed more effectively, and the possible damage caused by the impact is slowed down.

When the automobile seat headrest with the anti-whipping performance improved is formed, the supporting steel wires 3 are welded on the supporting cross bars 22, then the headrest framework 2 and the supporting steel wires 3 are put into a mold for foaming, and finally the outer side of the headrest foam 11 is coated with the skin 12.
