Embodiment approach 1

[0060] refer to Figure 2 ~ Figure 6 , the vehicle seat core material 2 according to Embodiment 1 of the present invention will be described.

[0061] figure 2 is from the vehicle mounting surface 3b side ( figure 1 The lower side in the middle) is a plan view of the vehicle seat core material 2 according to Embodiment 1 of the present invention.

[0062] Such as figure 2 As shown, the structure of the vehicle seat core material 2 is that there is a recessed space 7 on the surface of the in-mold foamed molded body 3 on the vehicle installation surface 3b side, and the insert 4 is inserted into the recessed space 7. The exposed part 8 of the insert is exposed. In addition, in this embodiment, as an example, the recessed space 7 is provided on the vehicle mounting surface 3 b of the in-mold foam molding 3 , but when the recessed space 7 is provided on the in-mold foam molding 3 The same configuration applies to the surfaces other than the vehicle mounting surface 3b. He...

[0085] Other embodiments of the present invention will be described as follows. In addition, for convenience of description, members having the same functions as those described in Embodiment 1 are given the same reference numerals, and description thereof will be omitted.

[0086] based on Figure 7 The vehicle seat core 2 in this embodiment will be described.

[0087] The recessed space 7 in this embodiment is provided on at least one of the seat surface 3a, the vehicle mounting surface 3b, and the side surface 3c of the in-mold foamed molded body 3, and is not in contact with a part of the body of the passenger. relative position. exist Figure 7 Among them, as an example, the recessed space 7 is provided on the vehicle installation surface 3b of the in-mold foam molding 3, but the recessed space 7 is provided on the vehicle installation surface 3b of the in-mold foam molding 3 The same structure applies to the other surfaces. According to this configuration, the reces...

Embodiment approach 3

[0089] Still another embodiment of the present invention will be described as follows. In addition, for convenience of description, members having the same functions as those described in Embodiments 1 and 2 are given the same reference numerals, and description thereof will be omitted. based on Figure 10 The vehicle seat core 2 in this embodiment will be described.

[0090] In the vehicle seat core material 2 of the present embodiment, among the seat surface 3a, the vehicle mounting surface 3b, and the side surface 3c on the surface of the in-mold foam molding 3, the occupant 17 does not touch the part of the body of the occupant 17 when the occupant 17 is on board. The opposite position is different from Embodiments 1 and 2 in that a recessed space 7 is arranged. Figure 10 (a) to (c) are diagrams schematically showing a situation in which the occupant 17 rides on the vehicle seat 1 having the vehicle seat core material 2 according to the present embodiment. exist Figu...

Abstract

The object of the present invention is to provide a vehicle seat core material, which can easily attach the surface cover of the vehicle seat to the vehicle seat core material, and can realize a connection that is not easily detached, and can be produced with a simple mold structure. The vehicle seat core material (2) of the present invention forms a recessed space (7) on the surface of the in-mold foam molding (3) constituting the vehicle seat core material (2), and the recessed space ( 7) Has an insert exposed part (8) and a protrusion (9) protruding toward the insert exposed part (8) inside, and has a gap (D) between the insert exposed part (8) and the protrusion (9) .

Description

technical field [0001] The present invention relates to a vehicle seat core material, a mold for forming a vehicle seat core material, and a method for manufacturing a vehicle seat core material. Background technique [0002] Conventionally, seats for vehicles (cars, etc.) are generally produced by embedding an insert made of metal or the like for shape stabilization in a seat body made of thermosetting polyurethane foam as a known technique. and integrally mold them (utility model document 1, patent document 1). However, in recent years, from the perspectives of vehicle weight reduction and cost reduction, a structure of an in-mold foamed molded article in which thermosetting polyurethane foam and inserts are partially replaced with thermoplastic resin foam particles has been proposed (utility model Document 2, Patent Documents 2-4). The reason for this is that the in-mold foamed molded article is lighter in weight than thermosetting polyurethane foam and metal, and has m...
