Abstract

The utility model provides a seat headrest assembly, which comprises a foaming framework, a guide rod for fixing and supporting the framework, and a buffering mechanism arranged on the framework for buffering the foaming, wherein the buffering mechanism can deform itself when being pressed so as to buffer the head. The buffer mechanism deforms to buffer foaming, so that the head is buffered. When the impact is received, when intensity is too big, the buffer tank on the welt realizes warping, can inwards or outwards warp, realizes the buffering to avoided the too high problem of skeleton rigidity, formed the protection to the head. The lining plate is arc-shaped, so that the head is convenient to gather towards the middle part, deflection is avoided, and better buffering and protection of the head and the neck are realized.

Description

Seat headrest assembly and car

Technical Field

The utility model relates to the field of automobile headrests, in particular to a seat headrest assembly and an automobile.

Background

With the development of the automobile industry, the attention of customers to passive safety performance and riding comfort of passengers is getting higher and higher, so as to reduce the injury value of the head and the neck of a driver of a collided vehicle in the low-speed rear collision process. At present, the headrest of the automobile seat mostly adopts a multidirectional adjusting structure, so that the gap between the head and the headrest in the whipping test process is reduced, and the protection effect of the headrest of the automobile seat on the head and the neck of a driver is improved. In severe collision, the headrest framework or the pad cannot be deformed to a certain extent, and even the situation that the head and the neck of a driver and a passenger are secondarily injured due to the too high rigidity of the headrest framework occurs.

Disclosure of Invention

The embodiment of the utility model aims to provide a seat headrest assembly and an automobile, which solve the problems in the background technology.

In order to achieve the above-mentioned purpose, an embodiment of the present utility model provides a seat headrest assembly, including a foam, a frame to mount the foam, a guide rod to fix the support frame, and a cushioning mechanism provided on the frame to cushion the foam, the cushioning mechanism being capable of deforming itself when pressed to cushion the head. The buffer mechanism deforms to buffer foaming, so that the head is buffered.

Optionally, the buffer gear is including installing the welt that supports the foaming on the skeleton, and the welt is sunken to the holding surface of head form the buffer tank, and the buffer tank runs through the welt, can warp in order to realize buffering through the buffer tank when the welt is pressed. The buffer groove can deform outwards or inwards when the lining plate is pressed, so that buffering is realized.

Optionally, a plurality of parallel buffer grooves are provided. The deformation effect is good.

Optionally, the buffer groove is vertically arranged in a plurality. The deformation effect is good.

Optionally, the section of the buffer groove is arc-shaped. Is easier to deform and is not easy to break.

Optionally, the lining plate is made of metal. The metal has high strength, is stronger and durable compared with plastics.

Optionally, the middle guide rod of the lining plate is sunken to be in a circular arc shape which is convenient for buffering the head towards the middle. The head is convenient to be gathered towards the middle part, so that the skew is avoided, and the foaming shape is circular arc along with the lining plate.

An automobile comprises the seat headrest assembly, wherein the seat headrest assembly can be a rear seat, and is used on the automobile, and of course, the seat headrest assembly is not limited to the automobile and can also be a truck or the like.

One of the above technical solutions has the following advantages or beneficial effects:

1. when the impact is applied, the buffer groove on the lining plate deforms to deform inwards or outwards to buffer the impact, so that the problem of overhigh rigidity of the framework is avoided, and the head is protected;

2. the lining plate is arc-shaped, so that the head is convenient to gather towards the middle part, deflection is avoided, and better buffering and protection of the head and the neck are realized.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident 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.

As shown in fig. 1 to 3, an embodiment of the present utility model provides a seat headrest assembly, which includes a foam 1, a frame 2 for mounting the foam 1, a guide rod 3 for fixing and supporting the frame 2, and a buffering mechanism disposed on the frame 2 for buffering the foam 1, wherein the buffering mechanism can deform itself when being pressed to buffer a head. The buffer mechanism deforms to buffer the foam 1, so that the head is buffered.

The buffer mechanism comprises a lining plate 4 which is arranged on the framework 2 and used for supporting the foaming 1, the supporting surface of the head of the lining plate 4 is sunken to form a buffer groove 41, the buffer groove 41 penetrates through the lining plate 4, and the lining plate 4 can deform through the buffer groove 41 when being pressed so as to realize buffering. The buffer groove 41 can deform outwards or inwards when the lining plate 4 is pressed, so that buffering is realized. The buffer tank 41 is provided in parallel in plural. The deformation effect is good. The buffer tank 41 is provided in plural vertically. The deformation effect is good. The buffer tank 41 has a circular arc-shaped cross section. Is easier to deform and is not easy to break. The lining plate 4 is made of metal. The metal has high strength, is stronger and durable compared with plastics.

The middle part of the lining plate 4 is concave towards the guide rod 3 and is in a circular arc shape which is convenient for buffering the head part towards the middle part. The head is convenient to be gathered towards the middle part, and the skew is avoided, and the foam 1 is in a circular arc shape along with the lining plate 4.

Working principle: when the impact is received, the buffer groove 41 on the lining plate 4 deforms to be inward or outward deformed when the strength is too high, so that buffering is realized, the problem of too high rigidity of the framework 2 is avoided, and the head is protected. The lining plate 4 is arc-shaped, so that the head is conveniently gathered towards the middle part, the skew is avoided, and better buffering and protection of the head and the neck are realized.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
