Description

  The present invention relates to an automobile seat in which a seat back and a seat cushion can be positioned and connected to each other.

  In general, an automobile seat is constituted by a seat back and a seat cushion connected to each other by connecting a side bracket of the seat back and a side bracket of the seat cushion with a stopper.

  Each side bracket is formed with a plurality of retaining holes for inserting fasteners such as a fastening bolt and a fastening pin. By the way, since the seat cushion and the seat back are heavy, it is necessary to perform extremely complicated work to align the stop holes with each other and to connect the seat cushion and the seat back with a stopper.

  The problem to be solved by the present invention is to position and connect the seat back and the seat cushion to each other.

  The present invention relates to an automobile in which a seat back and a seat cushion are connected to each other by connecting a side bracket protruding from the lower side portion of the seat back and a side bracket protruding from the rear side portion of the seat cushion with a stopper. The seat includes a positioning mechanism that can position the side bracket of the seat back and the side bracket of the seat cushion relative to each other when the seat back and the seat cushion are connected.

  The vehicle seat according to the present invention includes a positioning mechanism that helps to position the side bracket of the seat back and the side bracket of the seat cushion, so that the seat back and the seat cushion are connected to each other very easily and accurately. Can be made.

  In the present invention, the positioning mechanism includes a rod-shaped locking bracket extending from the side bracket of the seat cushion and a locking bracket receiving portion formed on the side bracket of the seat back. The side bracket of the seat back and the side bracket of the seat cushion can be positioned relative to each other by being locked to the portion. Thereby, the positioning mechanism can be configured very simply and inexpensively.

  Furthermore, the present invention is characterized in that the locking metal fitting is formed in a substantially U shape by extending from the back surface side to the front surface side of the side bracket of the seat cushion. As a result, the positioning work can be performed while inserting a part of the seat back bracket between the upper part of the substantially U-shaped locking bracket and the plate surface of the side bracket of the seat cushion. It can be done easily.

  The illustrated embodiment is configured as a reclining automobile seat. FIG. 1 is a side view of the sheet, and FIG. 2 is a longitudinal sectional view of the sheet. In the drawings, reference numerals B, C, 1 and 2 respectively indicate a seat back, a seat cushion, a side bracket projecting downward from the lower side portion of the seat back, and a side bracket projecting upward from the rear side portion of the seat cushion. .

The side bracket 1 that protrudes downward from the lower side portion of the seat back B has a first side bracket portion 1a and a second side bracket portion 1b that are opposed to each other with a space therebetween, and these first side brackets between the bracket portion 1a and the second side bracket portion 1b, actuation shaft R ₁ is the first and second side brackets portion 1a, the reclining mechanism R in a state of penetrating the 1b are arranged.

  The first side bracket portion 1a is connected to a seat back frame (not shown) of the seat back B, and rotates with respect to the second side bracket portion 1b connected to the side bracket 2 of the seat cushion C as will be described later. As a result, the seat back B can be reclined. The second side bracket portion 1b extends downward longer than the first side bracket 1a, and a plurality of retaining holes 4 through which fasteners 3 such as fastening bolts and fastening pins are inserted are formed on the lower plate surface. Has been.

  A plurality of retaining holes 5 through which the stoppers 3 are inserted are also formed on the plate surface of the side bracket 2 projecting upward from the rear side portion of the seat cushion C.

  This vehicle seat is provided with a positioning mechanism useful for positioning the second side bracket portion 1b of the seat back and the side bracket 2 of the seat cushion when the seat back B and the seat cushion C are connected. .

  The positioning mechanism includes a rod-shaped locking metal fitting 6 that extends from the rear surface side of the side bracket 2 of the seat cushion C toward the front surface side and is bent into a substantially U shape, and the second side bracket portion 1b of the seat back. It has the latching metal receiving part 7 provided.

  A raised portion 1b 'is formed along a part of the edge of the second side bracket portion 1b, and a notch formed by extending from the lower end portion of the raised portion 1b' in the plate surface direction of the second side bracket portion 1b. The latch metal receiving part 7 is comprised by the part.

  The locking bracket 6 and the locking bracket receiving portion 7 overlap the second side bracket portion 1b of the seat back B on the side bracket 2 of the seat cushion C in order to connect the seat back B and the seat cushion C, When the locking metal fitting 6 is engaged with the locking metal receiving part 7, the stop hole 4 of the second side bracket part 1b and the stop hole 5 of the side bracket 2 are provided at positions where they can be aligned with each other. ing.

  As described above, the locking metal fitting 6 extends from the back surface side of the side bracket 2 of the seat cushion C toward the front surface side and is bent in a substantially U shape, so that the second side bracket 1b of the seat back B is formed. The positioning operation can be performed while a part is inserted between the plate surface of the side bracket 2 of the seat cushion C and the upper portion of the locking metal fitting 6. With this positioning, the stopper 3 is inserted into the mutually aligned stopper holes 4 and 5 in a state where the stopper holes 4 of the second side bracket portion 1b and the stopper holes 5 of the side bracket 2 are aligned with each other. B and the seat cushion C can be connected.

  In each figure, reference numeral 8 urges the seat back B to automatically rotate the seat back B relative to the seat cushion C when the locking mechanism (not shown) of the reclining mechanism R is released. A spiral spring is shown. The spiral spring 8 is stretched between the first side bracket portion 1a and the second side bracket portion 1b of the seat back B. Reference numeral 9 denotes a seat belt fixed to the second side bracket portion 1b of the seat back B.

  In the vehicle seat according to the present invention configured as described above, when connecting the seat back B and the seat cushion C, the retaining hole 4 and the seat cushion C provided in the second side bracket portion 1b of the seat back B are provided. Since the seat back B and the seat cushion C are positioned so as to be aligned with the retaining holes 5 formed in the side bracket 2, the seat back B and the seat cushion C are extremely simple and It can be accurately connected.
