Problems solved by technology

[0004] However, in the above-mentioned technique of Japanese Patent Laid-Open No. 5-137629, since the side frame is completely crushed, the section modulus becomes low, and as a result, the strength of the side frame decreases.

Embodiment 3

[0049] Next, refer to Figure 5-6 Embodiment 3 of the present invention will be described. This Example 3 is an aspect which can more easily assemble a seat cushion (not shown) to the seat cushion frame 203 than the Example 2 already described.

[0050] like Figure 5 As shown, the seat cushion frame 203 of the driver's seat 201 in this embodiment 3 is also composed of the left and right side frames 10, 20 and the front bar 30, The rear rod 32 is formed by butt welding and has a substantially rectangular frame shape.

[0051] Here, the joining will be described in detail. In this third embodiment, the right rear part D among the four parts is described, and the description of the remaining three parts A, B, and C joined in the same manner as the right rear part D is omitted. In addition, for convenience of explanation, in the left and right side frames 10 and 20 , the places where the front bar 30 and the rear bar 32 are joined are referred to as joining parts 212 , 214 , ...

Abstract

The seat framework (3) for vehicle use comprises two circular tube-like components (20, 32), wherein the end face of one of the circular tube-like components (32) and the external surface of the other circular tube-like component (20) are combined via butt welding in a manner that the axes thereof are orthogonal to each other. Moreover, part of the external surface of the circular tube-like component (20), which is jointed with the end face of the circular tube-like component (32), is formed into a plane shape in a manner allowing the surface contact with the end face of the circular tube-like component (32) while ensuring the internal space (F) of the inner side of the external surface of the circular tube-like component (20).

Description

technical field [0001] The present invention relates to a seat frame for a vehicle, and specifically relates to a seat frame comprising two round pipe members, wherein the end face of one round pipe member is butt-welded with respect to the outer surface of the other round pipe member so that the axes of each other are perpendicular to each other. A combined vehicle seat frame. Background technique [0002] Conventionally, there is known a vehicle seat frame in which the end surface of one round pipe member is joined to the outer surface of the other round pipe member by butt welding so that their axes are perpendicular to each other. Here, the following Japanese Patent Laid-Open No. 5-137629 discloses a vehicle seat frame in which the end surface of a rod as one round pipe member can be opposed to a side frame as another round pipe member. The outer surface is in surface contact, and the outer surface of the side frame is crushed into a flat shape. Thereby, the joining st...
