Description

Technical Field

[0001] The utility model relates to the technical field of vehicle seats, in particular to a foam fixing structure for vehicle seats and a vehicle seat. Background Art

[0002] As safety performance accounts for an increasingly large proportion in the minds of consumers, the functions of seats are constantly upgraded, and the configuration of side airbags plus remote airbags is becoming more and more common. However, due to the generally large volume of the remote airbag, after overall assembly, the seat flanks will sag severely outward, and even directly interfere with the vehicle's center console armrest, affecting the delicate feeling and generating frictional noise at the same time. Over time, it will cause the center console and the seat to fade.

[0003] At present, a relatively common improvement method is to weld steel wires on the seat frame and push against the flank foam from the outside so that the overall shape will not sag too severely. However, on the one hand, this method will reduce the flank indentation amount, which not only affects the comfort of passengers but also occupies the space of the foam body, resulting in the inability of the foam to be formed. On the other hand, the foam will fix the entire flank, and the flank cannot deform inward during whipping, affecting the amount of human body indentation and being unfavorable for whipping.

[0035] Such as Figures 1 - 5As shown, a foam fixing structure for a car seat is particularly convenient for application at the two side wings of a car seat. It mainly comprises: a seat frame 1, a foam body 2, a connecting strap 3 and a fixing member 4.

[0036] The foam body 2 is provided with a connecting buckle 20. Specifically, the connecting buckle 20 is integrally foamed with the foam body 2. During the foaming process, the connecting buckle 20 is placed in a foaming mold so that it is integrally foamed with the foam body 2 without changing the shape of the foam body 2. The connecting buckle 20 is made of metal, and after being integrally foamed with the foam body 2, it protrudes from the back side of the foam body 2, which is convenient for assembly and fixing from the back side of the seat back.

[0037] The connecting strap 3 passes through the connecting buckle 20 and is connected to the connecting buckle 20, and the end of the connecting strap 3 away from the connecting buckle 20 is fixed to the seat frame 1 through the fixing member 4, so that the foam body 2 is fixed to the seat frame 1. Specifically, as Figure 3 As shown, the seat frame 1 is provided with a fixing hole 10, and the fixing hole 10 is used for installing the fixing member 4. Figure 4 and Figure 2 As shown, both ends of the connecting strap 3 are provided with a through hole 30. One end of the connecting strap 3 passes through the connecting buckle 20 and then goes around to the other end thereof, so that the through holes 30 at both ends thereof are aligned. The fixing member 4 passes through the two through holes 30 to fix the connecting strap 3 in the fixing hole 10 on the seat frame 1, so that the connecting strap 3 is fixed on the seat frame 1. The connecting strap 3 in this embodiment is a flexible member, preferably made of PP material (i.e., polypropylene), which has high impact resistance and strong mechanical properties. The strap has the characteristic of unidirectional tensioning, which does not affect the depression of the human body. It can effectively improve the comfort and whipping performance of the car seat. There is no need to weld steel wire on the seat frame 1 to support the foam body 2 from the outside, and the car seat will not have a large weight increase (the total weight of the connecting strap 3 and the fixing member 4 is about 15g).

[0038] In this embodiment, the length of the connecting strap 3 can be adjusted according to actual installation requirements, so that the foaming body 2 can be conveniently fixed regardless of whether the space is narrow, long, or complex, and the adaptability is wide.

[0039] Preferably, the fixing part 4 used in this embodiment is a Christmas tree buckle, which is a universal part. The Christmas tree buckle includes a connected fixing head 40 and a fixing rod 41. The fixing rod 41 is provided with a plurality of inclined blocks 410. The blocks 410 gradually tilt outward from the end away from the fixing head 40 to the end close to the fixing head 40, ensuring that the Christmas tree buckle is smoothly inserted into the seat frame 1, and the plurality of blocks 410 ensure that it will not detach from the seat frame 1, and the fixing effect is good.

[0040] The overall manufacturing and assembly process of the foaming fixing structure in this embodiment is as follows: First, the metal connecting buckle 20 is arranged in the foaming mold, so that the connecting buckle 20 and the foaming main body 2 are foamed and molded together, and the connecting buckle 20 is exposed on the back side of the foaming main body 2. After passing the connecting strap 3 made of PP material through the connecting buckle 20, it is folded in half so that the through holes 30 at both ends are aligned. The fixing member 4 passes through the two through holes 30 at both ends of the connecting strap 3 and is fixed in the fixing hole 10 of the seat frame 1 to complete the installation.

[0041] In this solution, a connecting buckle 20 is integrally foamed and molded on the foaming main body 2. The strap passes through the connecting buckle 20 and is connected to the connecting buckle 20. Both ends of the strap are fixed on the seat frame 1 through the fixing member 4, that is, the foaming main body 2 is fixed to the seat frame 1 through the connecting rod and the fixing member 4. Compared with the prior art, the strap has the characteristic of one-way tension, which does not affect the indentation of the human body, and can effectively improve the comfort and whiplash performance of the car seat; the length of the connecting strap 3 is adjustable and has a certain flexibility, and the foaming main body 2 can be fixed at a relatively long distance and in a complex space, which is convenient to fix and has a wide application range; and there is no need to change the shape of the foaming main body 2.
