DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to improvement of a vehicle seat.

(Prior Art) Conventionally, in a wagon type automobile, as shown in FIG. 9, a front seat 1 and a rear seat 2 are provided, and a recess 5 for a leg space formed in a luggage compartment floor 4 behind the rear seat 2 is provided. On the other hand, the third seat (auxiliary seat) 3 is provided back to back with the rear seat 2,
As shown in the figure, the seat back 3a of the third seat 3
It has been proposed that the seat cushion 3b is tilted and the opening of the recess 5 is closed by the seat back 3a and the seat cushion 3b so that the luggage space 6 behind the rear seat 2 can be flattened.

If the seat cushion 2b of the rear seat 2 is flipped forward and the seat back 2a without the headrest 2c is tilted forward, the luggage space 6 behind the front seat 1 can be further expanded.

(Problems to be solved by the invention) By the way, as shown in FIG. 11, on the back surface of the seat back 3a of the third seat 3 and the bottom surface of the seat cushion 3b, when the opening of the recess 5 is closed, the cargo room floor 4 is closed. A lid plate (thick veneer plate or the like) 7 that forms a part of each is attached, but the outer edge portion of the lid plate 5 has the same shape as the seat back 3a and the seat cushion 3b housed in the recess 5. Since it was set, due to variations in manufacturing and assembly, the cover plate 7
A gap t is formed between the outer edge of the recess 5 and the inner edge of the opening of the recess 5,
There was a problem that it looked bad.

The present invention has been made to solve the above problem, and when the opening of the leg space recess on the luggage compartment floor is closed by the seat back and seat cushion of the auxiliary seat, the space between the lid plate and the opening of the recess is provided. The purpose is to make it difficult to see the gap.

(Means for Solving the Problem) Therefore, according to the present invention, an auxiliary seat is provided back to back with respect to a recess for a leg space formed on a luggage compartment floor behind the seat, and the auxiliary seat is provided. In an automobile seat capable of flatly expanding the luggage compartment space behind the seat by tilting the auxiliary seat to close the opening of the recess, the recess is formed on the back surface of the auxiliary seat and the bottom surface of the seat cushion. Lid plates that form a part of the luggage compartment floor are attached when the openings of the lids are closed, and the inner edge portions of the openings before and after the recessed portion have outer edges of the front and rear edges of the lid plates when the openings are closed. Each of the lid plates is formed with a stepped portion, and the left and right outer edge portions of each of the lid plates are located slightly inside the left and right opening inner edge portions of the recess. In the end portions facing each other when the opening is closed, the lid plate end portion of the seat cushion bottom surface is located rearward of the joint between the seat back rear surface and the seat cushion bottom surface to form a receiving portion, The end portion of the lid plate on the back of the seat back is extended by a predetermined amount rearward of the seam to form an extension portion, and when the opening is closed, the extension portion is supported by the receiving portion and the front and rear portions. The outer edge portion is characterized in that the portion protruding outward from the inner edge of the step portion by a predetermined amount is supported by the step portion.

(Effects and effects of the invention) In the invention, the seat back of the auxiliary seat and the cover plate of the seat cushion are arranged such that the outer edge portions on the left and right sides are more than the inner edge portions on the left and right sides of the recess for the leg space formed on the luggage compartment floor. It is located slightly inside, and when the opening is closed, the front and rear outer edges are set to project outside the inner edge of the step by a predetermined amount, and the opening of the recess is closed by the seat back and seat cushion. At this time, since the outer edge portion of the lid plate is fitted into the step portion of the inner edge portion of the opening of the recess, it is difficult to see the gap between the outer edge portion of the lid plate and the inner edge portion of the opening of the recess.

In particular, in the front and rear opening edges, even if the outer edge of the lid plate and the inner edge of the opening of the recess vary during manufacturing and assembly, the outer edge of the lid plate becomes the step of the inner edge of the opening. Since it is fitted, it becomes difficult to see the gap and the appearance is improved.
