The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figures 1 to 5, a kind of backrest of automotive seat, comprise backrest frames, this skeleton has the shell 11 of " U " shape and the crossbeam 12 of connected with outer casing 11 both sides circumferentially extending along it, on the shoulder of shell 11, be rotatably connected to safety strap guide plate 20, and the support spring 30 of restriction safety strap guide plate 20 rotational angle on shell 11 shoulders, specifically can be at a square stay bearing plate 40 towards shell 11 bottoms of safety strap guide plate 20 1 side welding, the two ends of support spring 30 are connected on the both sides of shell 11, the support portion of support spring 30 31 is resisted against on stay bearing plate 40.Concrete, support spring 30 in the utility model has the anchor portion 32 of bending, and the support portion 31 that connects two anchor portion 32, this support portion 31 has some linear portions 33 that connect successively, the supporting section 34 that is " ︹ " shape that connects linear portion 33, is connected the linear portion at 31 two ends, support portion 33 respectively in obtuse angle with two anchor portion 32.The utility model is by being arranged on safety strap guide plate 20 in the side of shoulder of skeleton, when using of seat belts, no matter where backrest is adjusted to and which kind of angle, safety strap guide plate 20 is together adjusted with backrest all the time on the shoulder of skeleton, guarantees that both remain on best, safest position relationship.Because safety strap is to pull out from safety strap guide plate 20 and pass from taking-up device, therefore, safety strap can produce friction with safety strap guide plate 20, can not very glibly safety strap be pulled out, therefore, in the utility model, safety strap guide plate 20 is rotatably connected on the shoulder of shell 11, when safety strap guide plate 20 is pulled out safety strap, the direction that safety strap guide plate 20 can be pulled out along safety strap is rotated and is adjusted its angle in shoulder portion outside, with the friction of less generation, for avoiding safety strap guide plate 20 to rotate arbitrarily on the shoulder of shell 11, can limit its rotational angle on shell 11 shoulders by support spring 30, between the support portion 31 of the support spring 30 in the utility model and anchor portion 32, there is elastic stress, make support portion 31 can press to anchor portion 32, also can turn up towards the outside of anchor portion 32, and under the effect of this elastic stress, recover state of nature, therefore, the support portion of support spring 30 31 is connected on stay bearing plate 40, when safety strap guide plate 20 is when rotating, utilize the elastic stress of support spring 30 self, make the safety strap guide plate 20 after rotating revert to its optimum position on shell 11 shoulders.
Preferably, in the utility model, between shell 11 both sides, be horizontally connected with several rows tightening device from top to bottom, this tightening device comprises the extension spring 52 that the tension spring hook 51 that is arranged on shell 11 both sides inner sides and two ends are hooked in respectively the wave-like in tension spring hook 51, concrete, for providing the bearing force from waist to shoulder to occupant better, can between shell 11 both sides, be horizontally connected with this tightening device of three row from top to bottom.Occupant is when riding in an automobile seat, occupant's back is to be pressed on the backrest of seat, can to backrest applied pressure, there is corresponding deformation according to occupant in the extension spring 52 of wave-like, thereby provide corresponding bearing force, and the extension spring 52 of wave-like is larger with the area that occupant back contacts, can not make occupant feel uncomfortable.
Further, backrest of the present utility model also comprises the backrest base 61 being arranged on shell 11 both ends, and shell 11 two ends are pivotally attached on base 61 by connection angle regulating part 62 respectively, between two bases 61, be horizontally connected with the rotating shaft 63 that runs through two angle adjusting pieces 62, wherein an angle adjusting piece 62 is provided with the permanent seat 65 of fixed electrical machinery 64, orders about rotating shaft 63 drive two angle adjusting pieces 62 respectively along two base 61 upsets by motor 64.It is this area conventional means that motor 64 drives the drive mechanism of backrest upset adjusting angle of backrest, no longer describes in detail herein.Concrete, it is pressed on respectively to the U-shaped plate 80 on shell 11 two ends being also connected with between two angle adjusting pieces 62, the outside of two angle adjusting pieces 62 is wrapped up respectively in the two side of U-shaped plate 80, prevent two angle adjusting pieces 62 when driving backrest frames to rotate with shell 11 generation relative displacemenies.
Further, on the shoulder of shell 11, be also provided with the sleeve pipe 70 that headrest guide sleeve is installed, specifically can on the shoulder of shell 11, offer the positioning groove 13 mating with sleeve pipe 70, the outer wall of sleeve pipe 70 is welded in positioning groove 13, easily processing and manufacturing.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine technical scope according to claim scope.
