Abstract
The invention provides a seat headrest framework, which comprises a headrest framework reinforcing plate and a U-shaped support pipe, wherein the U-shaped support pipe is fixed in the middle of the back of the headrest framework reinforcing plate and is used for supporting a backrest; the seat headrest framework also comprises a headrest pipe and a headrest framework reinforcing rod; two vertical C-shaped grooves are punched at both ends of the headrest framework reinforcing plate; the headrest pipe is in an n shape, and both edges of the headrest pipe are embedded into the C-shaped grooves and are fixed by welding; and the headrest reinforcing rod passes through a punching hole in the middle of the headrest framework reinforcing plate, extends out of the back of the headrest framework reinforcing plate and is in welded connection with the reinforcing plate. The headrest framework is welded with a meshed framework to install the framework for the integral backrest; and the reinforcing rod on the headrest framework provides the support of headrests so as to prevent the headrests of passengers from moving backward due to inertia in the process of forward collision and can prevent the headrests from displacing excessively and overturning while protecting heads of the passengers.
Description
Technical field
The invention belongs to the auto body technical field, be specifically related to a kind of seat headrest framework structure.
Background technology
In automotive development, seat is one of main safety performance spare, and its intensity is had higher designing requirement.Headrest is as head restraint, and the head protection to the occupant in collision has played important effect.General back seat fixed type headrest features is simple, as shown in Figure 4, its by with the connecting panel 41 of backrest welding be affiliated to steel wire 42 and form, be affiliated to steel wire 42 and be welded on connecting panel 41 back sides.The headrest of this fixed sturcture, its intensity be " headrest and anchor fitting thereof should guarantee when the a/s method of static testing is measured, and the amount of moving X should be less than 102mm after the maximum of head dummy " in satisfying GB15083-2006, can not reach requirement.And if back seat is adopted active head restraint, can aspect intensity, have significantly to promote, can reach laws and regulations requirement, but cost can increase thereupon.
Summary of the invention
The technical matters that utility model solved can improve the headrest frame strength for a kind of seat headrest framework is provided, and can also the installation skeleton be provided for back of seat.
The technical scheme that the present invention adopted is following:
A kind of seat headrest framework, it includes headrest skeleton brace panel and the U type is affiliated to pipe, and said U type is affiliated to the middle part, the back side that pipe is fixed on headrest skeleton brace panel, is used for backrest and is affiliated to.It also includes headrest pipe and headrest skeleton stirrup; Two ends punching press at said headrest skeleton brace panel has two vertical C type grooves, and the headrest pipe is the n type, and its both sides are embedded in the C type groove, and fixing through welding; Said headrest skeleton stirrup passes the punching hole at headrest skeleton brace panel middle part, and stretch out at the occipital bone frame brace panel back side headward, is welded to connect with headrest skeleton brace panel.
Said headrest skeleton stirrup has two, two headrest skeleton stirrup horizontal arrangement, and be parallel to each other.
Above-mentioned headrest skeleton is through being welded to connect on the top of backrest mesh skeleton, and is as shown in Figure 2, the common frame assembly that supports whole backrest of forming.The U type of headrest skeleton is affiliated to pipe hanger and is leaned against on the installation hook of vehicle body, and is as shown in Figure 3, provides the installation of backrest assembly to support.
Effect of the present invention is: after headrest skeleton and the mesh skeleton welding, for whole backrest provides the installation skeleton, the stirrup on the headrest skeleton provides the support of headrest, prevents preceding bumping in the process, and occupant's headrest is because inertia backward, provides the protection of head for the occupant.The headrest that can reach GB15083 simultaneously prevents the requirement that displacement is excessive and overturn of resting the head in the racking test backward, strengthens the safety guard-safeguard effect of the many occupant's head of headrest.

Wherein, the 1-skeleton of resting the head on, 2-seat mesh back rest skeleton, the 11-pipe of resting the head on, 12-headrest skeleton stirrup, 13-headrest skeleton brace panel, the 14-U type is affiliated to pipe, 31 vehicle bodies, 32 back of seats are installed hook, the connecting panel that 41-and backrest skeleton weld, 42-is affiliated to steel wire
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified:
As shown in Figure 1, this seat headrest framework is affiliated to pipe 14 through being welded to form by headrest pipe 11, headrest skeleton brace panel 13, headrest skeleton stirrup 12 and U type.Headrest skeleton brace panel 13 integrated mechanisms as whole headrest skeleton have certain requirement to its intensity and structure design, and it adopts the ST12T=2mm steel drift molded.The two ends punching press of headrest skeleton brace panel 13 has two vertical C type grooves, the both sides of n type headrest pipe 11 is embedded in the C type groove, and fixing through welding, make headrest pipe 11 be fixed on the headrest skeleton brace panel 13.Two headrest skeleton stirrups 12 pass the punching hole of two levels at brace panel middle part, and stretch out at occipital bone frame brace panel 13 back sides headward, are welded to connect with brace panel, and two headrest skeleton stirrups 12 will be parallel to each other.The U type is affiliated to pipe 14 and is used for being affiliated to backrest, and the opening that it passes the brace panel middle part is fixed by welding in headrest skeleton brace panel 13 back sides.
As shown in Figure 2, headrest skeleton 1 and mesh back rest skeleton 2 are through being welded to form the backrest frame assembly.Headrest pipe 11 can support the headrest foam of enough height; The headrest skeleton is as the architecture basics of backrest frame assembly; It is cores of this structure design that headrest skeleton brace panel 13, headrest skeleton stirrup 12 and U type are affiliated to pipe 14; Play the effect that installs and fixes with stressed support, as shown in Figure 3, the backrest frame assembly is affiliated to pipe 14 through the U type and is affiliated on vehicle body installation hook 32.In headrest skeleton loading process, headrest skeleton stirrup 12 plays stressed support and inverting action.As shown in Figure 5, after the backrest assembly was assemblied on the vehicle body, there were gap, the 2mm left and right sides in headrest stirrup and vehicle body; Headrest brace panel and backrest are installed hook and are also had certain clearance; Under the power effect of F=373Nm (among the figure shown in the arrow), the headrest skeleton is stressed to be moved backward, and the headrest stirrup can contact with vehicle body 31; The headrest brace panel can be installed hook with backrest and contact; Through stirrup and the combined action of headrest brace panel, vehicle body will carry out effective support to headrest, can prevent its over-travel and upset.
