Background technology

Automotive seat belongs to the basic device of automobile, is the important safety component of automobile.It is by human body and vehicle in the car Body links together, and multiplies personnel, the shock and vibration that mitigation and attenuation are transmitted by vehicle body for supporting rack.With the hair of automobile The continuous improvement of exhibition and people's requirement, automotive seat have no longer been the simple car body component for meeting and taking with beautiful needs, but It is related to ride comfort and the safety of automobile, integrates ergonomics, mechanical oscillation, the system engineering for controlling engineering Product.As the important inner-decoration component for influencing car comfort and safety, design, the research and development of automotive seat are increasingly drawn The attention of automobile industry is played, above works hard, has developed each in the new construction of seat, new process, the research and development of new material and application Class novel seat, in addition, will also become a kind of new trend as seat-cover fabric using environment-friendlyfabric fabric.

Car seat headrest is a kind of auxiliary device set to improve automobile ride comfort and safety, headrest Main function is to ensure safety, once automobile collides, cervical vertebra can bear very big acceleration and easily come to harm.According to having Department statistics are closed, in the traffic accident, neck strain is one of most common injury.Data is shown, in 26% rear-end collision, is driven The head or neck for multiplying personnel can be damaged, and under equal conditions, proper use of automotive headrest uses automobile than incorrect Driver and passenger's neck of headrest feels that the probability of pain reduces 40%, the support for having headrest, it is possible to reduce head is free-moving Space reduces the impact force to cervical vertebra, plays the role of avoiding or mitigates occupant's whiplass.

In the prior art, headrest fixed seat is circular tube structure, is contacted with welding contact site for line, it is understood that there may be welding product The problem of matter is unstable；And panel beating needs to complete by multistep.

Utility model content

The technical issues of in order to solve car seat headrest connection in the prior art, the utility model provides a kind of seat head Rest the head on connection structure, it is possible to reduce the assembling error in production process improves the quality of product, simplifies the process of panel beating, tool Body scheme is as follows：

A kind of chair headrest connection structure, including headrest fixed seat and headrest fixing sleeve, which is characterized in that the pillow holder Reservation is rhs-structure, and the rhs-structure carries out mistake proofing using different R angles radians, and the headrest fixed seat is fixed on seat On the upper beam of backrest frames, the headrest fixed seat is contacted with fixed contact position for face；The fixed inserting of headrest is set on In the headrest fixed seat.

Further, four angles of the rhs-structure cross section are one small R angles, one big R angles and two right angles.

Preferably, the headrest fixed seat is two, on the seat back-rest framework upper beam there are two with the headrest The concave surface that fixed seat matches, the face between described two right angles of rhs-structure are in contact with the concave surface.

Further, the middle part of the headrest fixed seat is in contact fixation with the seat back-rest framework upper beam, described Seat back-rest framework upper beam is vertical fixed with the headrest fixed seat.

Preferably, two headrest fixed seats are symmetrically fixed on the seat back-rest framework upper beam, two big R Angle is opposite.

Further, to be welded and fixed, the manufacturing procedure of the rhs-structure mainly adds the fixed form including steel pipe Work and Pipe Cutting.

Implement the utility model embodiment, have the advantages that：

1st, it is designed using mistake proofing, mistake proofing is carried out using different R angles radians, reduces the error in assembling process；

2nd, the headrest fixed seat is rhs-structure, is contacted with the welding position of contact surface for face, welding quality is stablized；

3rd, the process of panel beating is simplified, and mainly includes steel pipe processing and Pipe Cutting.

Description of the drawings

Fig. 1 is the utility model chair headrest attachment structure schematic diagram；

Fig. 2 is the schematic diagram of the utility model headrest fixed seat；

Fig. 3 is the schematic diagram of the utility model seat framing structure.

Wherein, the reference numeral in figure is：1- headrest fixed seats, 2- headrest fixing sleeves, 3- seat back-rest framework upper beams, 4- seat back-rest frameworks, the small R angles of 5-, the big R angles of 6-, 7- seat cushion frameworks, 8- connectors, 9- recliners.

Specific embodiment

It is new to this practicality below in conjunction with attached drawing to make the purpose of this utility model, technical solution and advantage clearer Type is described in further detail.

Fig. 1 be the utility model chair headrest attachment structure schematic diagram, Fig. 2 be rest the head on fixed seat schematic diagram, from Fig. 1 with A kind of chair headrest connection structure is can be seen that in Fig. 2, including headrest fixed seat 1 and headrest fixing sleeve 2, which is characterized in that institute It is rhs-structure to state headrest fixed seat 1, and the rhs-structure carries out mistake proofing, the headrest fixed seat 1 using different R angles radians It is fixed on the upper beam 3 of seat back-rest framework, the headrest fixed seat 1 is contacted with fixed contact position for face；The headrest Fixing sleeve 2 is inserted in the headrest fixed seat 1.

Further, four angles of the rhs-structure cross section are one small 5, the big R angles 6 in R angles and two right angles.

Further, the headrest fixed seat 1 is two, on the seat back-rest framework upper beam 3 there are two with it is described The concave surface that matches of headrest fixed seat 1, the face between described two right angles of rhs-structure are in contact with the concave surface.

Preferably, the middle part of the headrest fixed seat 1 is in contact fixation with the seat back-rest framework upper beam 3, described Seat back-rest framework upper beam 3 is vertical fixed with the headrest fixed seat 1.

Further, two headrest fixed seats 1 are symmetrically fixed on the seat back-rest framework upper beam 3, two Big R angles are opposite.

Preferably, to be welded and fixed, welding contact site contacts the fixed form for face, improves the quality of welding, Connection is more fixed.The manufacturing procedure of the rhs-structure is also simplified, and mainly includes steel pipe processing and Pipe Cutting.

Automotive seat is generally made of headrest, backrest, regulating device, seat cushion and seat connection etc., and Fig. 3 is chair framework The schematic diagram of structure, from figure 3, it can be seen that automobile chair frame is generally by seat back-rest framework 4, seat cushion framework 7 and headrest The compositions such as connection structure.The headrest connection structure is fixed on the seat back-rest framework upper beam 3, and head pillow frame passes through head Connection structure is rested the head on to be mounted on seat back-rest framework 4.The seat back-rest framework 4 and the seat cushion framework 7 pass through 8 phase of connector Even, and by recliner 9 angle of seat back-rest framework 4 is adjusted.Height, the shape of the backrest meet human body song Line, and effectively can reliably be supported to back and shoulder, the support of also enough side backs makes driver and passenger keep stable seat Appearance.Headrest play the role of protect cervical vertebra, correct installation site is particularly significant, headrest should be mounted at least with ear top The concordant place of edge, the distance between hindbrain and headrest are preferably not more than 10cm.

The advantage of the utility model is, is designed using mistake proofing, carries out mistake proofing by different R angles radians, reduces dress With error in the process, welding quality is stablized, and improves the quality of product, and the process of panel beating is simplified.

Above disclosed is only a kind of the utility model preferred embodiment, cannot limit this practicality with this certainly Novel interest field, therefore the equivalent variations made according to the utility model claims, still belong to what the utility model was covered Range.
