  By the way, the rear end portion of the cushion pad of the seat cushion is typically disposed so as to sink under the cushion pad of the seat back and cover the hinge shaft that supports the seat back in a tiltable manner. For this reason, the rear end portion of the cushion pad of the seat cushion covering the hinge shaft is formed thinner than the seat surface portion. However, the rear end portion of the cushion pad of the seat cushion is formed with a thin shape and further has a formability after molding to obtain a desired shape due to the provision of a hole through which the buckle of the seat belt is passed. It was inferior in shape reproducibility to hold

  In the seat assembling process, the hinge shaft and the buckle are usually fixed to the floor panel, and then the seat cushion is fixed to the floor panel. In order for the buckle to be smoothly inserted into the cushion pad hole of the seat cushion, the buckle needs to be positioned, and when the buckle support member is flexible, additional work such as hanging the buckle is required. However, the assembly work of the sheet was complicated.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to improve the formability and shape reproducibility of a cushion pad of a seat cushion and improve the workability of seat assembly.

  A vehicle seat according to an aspect of the present invention is provided with a seat cushion fixed to a vehicle body, a seat back tiltable with respect to the seat cushion, and fixed to the body and disposed on a seating surface of the seat cushion. A seat belt buckle, and a cushion pad of the seat cushion covers a first pad that forms the seat surface and a hinge shaft that supports the seat back in a tiltable manner, and is adjacent to the first pad. And the seat belt buckle is disposed on the seat surface through the space between the first pad and the second pad.

  ADVANTAGE OF THE INVENTION According to this invention, while the moldability and shape reproducibility of the cushion pad of the seat cushion of a vehicle seat can be improved, the workability | operativity of a seat assembly can be improved.

It is a perspective view showing an example of a vehicle seat for explaining an embodiment of the present invention. It is a disassembled perspective view of the seat cushion shown in FIG. It is AA sectional drawing of FIG.

  FIGS. 1 to 3 show an example of a vehicle seat (hereinafter also simply referred to as “seat”) for describing an embodiment of the present invention.

  A seat 10 shown in FIGS. 1 to 3 is a vehicle seat mounted on a vehicle (vehicle) such as an automobile, and is a bench-type rear seat that is disposed on the rear side of the vehicle and on which a plurality of passengers can sit side by side.

  The seat 10 is fixed to the body (main body) of the vehicle, is provided with a seat cushion 20 for supporting the occupant's buttocks and thighs of the occupant seated on the seat 10, and is tiltable with respect to the seat cushion 20. A seat back 30 for supporting the waist and the back, and a buckle 53 of the seat belt 50 for restraining an occupant to the seat cushion 20 and the seat back 30 are provided.

  The seat belt 50 includes a belt-like flexible webbing 51, a tongue 52 through which the webbing 51 is inserted, and a buckle 53 that detachably locks the tongue 52. The buckle 53 is fixed to the body via a fixing member 54 (see FIGS. 2 and 3). The fixing member 54 may be a relatively rigid member or a flexible member similar to the webbing 51. In the seat 10 on which a plurality of occupants can be seated, a seat belt 50 is provided for each occupant, and a plurality of buckles 53 are also provided.

  The seat cushion 20 includes a metal cushion frame 21 (see FIG. 3) that forms a skeleton (base) of the seat cushion 20. The cushion frame 21 is covered with a cushion pad 22 made of a relatively soft resin foam material such as urethane foam, and the cushion pad 22 is further covered with a trim cover made of a skin material such as leather, woven fabric, and non-woven fabric. ing.

  The seat back 30 is configured in the same manner as the seat cushion 20, and includes a back frame that forms a skeleton of the seat back 30. The back frame is covered with a cushion pad, and the cushion pad is further covered with a trim cover. . The seat back 30 is provided so as to be tiltable with respect to the seat cushion 20 with a metal hinge shaft 40 disposed at the lower end of the seat back 30 as a rotation axis.

  A pair of fixing brackets 41 for fixing the hinge shaft 40 to the body are provided at both ends of the hinge shaft 40 (see FIG. 2). The hinge shaft 40 is provided with a plurality of anchors 42 for fixing the child seat. The plurality of anchors 42 are provided on the outer peripheral surface of the hinge shaft 40 at intervals in the axial direction.

  The cushion pad 22 of the seat cushion 20 is divided into a first pad 23 and a second pad 24. The first pad 23 forms a seating surface of the seat cushion 20, and the second pad 24 covers the outer peripheral surface of the hinge shaft 40, and is adjacent to the rear end portion of the first pad 23.

  In this example, the second pad 24 covering the outer peripheral surface of the hinge shaft 40 is formed integrally with the hinge shaft 40. Such a second pad 24 can be formed by integral foaming, for example. In the integral foam molding, the hinge shaft 40 is placed in a predetermined mold, and in this state, a foam resin is injected into the mold, and the injected foam resin is foamed in the mold to perform the molding. As described above, a plurality of anchors 42 are provided on the outer peripheral surface of the hinge shaft 40, and the second pad 24 has a plurality of openings 25 that expose the plurality of anchors 42.

  The rear end portion of the first pad 23 forming the seating surface of the seat cushion 20 is disposed below the hinge shaft 40, and in the vertical direction with the second pad 24 covering the outer peripheral surface of the hinge shaft 40. overlapping. The thickness of the first pad 23 is gradually decreased from the front end toward the rear end so as to incline the seating surface of the seat cushion 20, but is larger than the thickness of the second pad 24 over the entire first pad 23. . Since the thickness of the 1st pad 23 which forms the seat surface of the seat cushion 20 can be ensured over the whole 1st pad 23, the shape reproducibility which maintains the moldability of the 1st pad 23 and the shape after shaping | molding is improved. be able to.

  A plurality of buckle storage portions 26 are formed at the rear end portion of the first pad 23. The buckle storage portion 26 corresponds to the arrangement of the plurality of buckles 53 and is provided at intervals in the seat width direction. The buckle housing portion 26 is formed by notches opened on the upper and lower surfaces and the rear surface of the first pad 23. However, the opening edge of the buckle housing portion 26 on the upper surface of the first pad 23 is closed by the second pad 24 that overlaps the rear end portion of the first pad 23, and the buckle housing portion 26 has the first pad 23. 23 and the second pad 24 are combined to form a hole.

  Hereinafter, the assembly process of the sheet 10 will be described.

  First, the hinge shaft 40 on which the second pad 24 of the seat cushion 20 is integrally formed is fixed to the body via the pair of fixing brackets 41, and the buckle 53 is fixed to the body via the fixing member 54. The first pad 23 of the seat cushion 20 is fixed to the body via the seat cushion frame while the hinge shaft 40 and the buckle 53 are fixed to the body, and the first pad 23 is attached to the body via the seat cushion frame. When fixed, the buckle 53 is accommodated in the buckle accommodating portion 26 of the first pad 23, and the buckle 53 is disposed on the seating surface of the seat cushion 20 through between the first pad 23 and the second pad 24.

  Here, when the buckle 53 is displaced in the seat width direction with respect to the buckle storage portion 26, the buckle 53 is sandwiched between the rear end of the first pad 23 and the second pad 24, but they are separated from each other. The slit between the rear end of the first pad 23 and the second pad 24 is a continuous slit in the sheet width direction and communicates with the buckle storage portion 26. Therefore, for example, the buckle 53 can be accommodated in the buckle accommodating portion 26 by appropriately deforming the fixing member 54 and moving the buckle 53 along the slit. Thus, since the exact positioning of the buckle 53 is unnecessary, the workability of assembly can be improved. In particular, when the fixing member 54 is a flexible member similar to the webbing 51, the buckle 53 cannot be held at a predetermined position by the fixing member 54, so that the buckle 53 does not need to be positioned precisely. Is particularly useful for improving workability.

  In addition, since the second pad 24 and the hinge shaft 40 are integrally formed, it is possible to save the trouble of covering the second pad 24 on the hinge shaft 40, and to further improve the workability of the assembly. Further, since the second pad 24 and the hinge shaft 40 are integrally formed, the positioning of the second pad 24 for matching the opening 25 and the anchor 42 is not necessary, so that the assembly workability is improved. It can be further enhanced.

  In addition, the said structure of the vehicle seat 10 installed in vehicles, such as a motor vehicle, is applicable also to the vehicle seats other than vehicles, such as a ship and an aircraft.
