Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a seat device for an automobile, and particularly to a seat device that is tiltable in order to expand the cargo space.

(Prior Art) In automobiles for both cargo and passenger use, a structure is adopted in which a seat device can be tilted freely so that the cargo space can be expanded as needed. For example, in the case of a cab-over one-box car,
As disclosed in Japanese Utility Model Application No. 55-119231, by standing the seat cushion and seat back of the rear seat behind the front seat in a folded state, the front seat can be moved while avoiding the engine located under the front seat. It is possible to expand the floor area of the luggage compartment behind the seat.

However, even if it is a one-box car, in the case of a light vehicle equipped with an MR (midship rear drive) engine, it is necessary to secure engine space below the rear seat, so the floor panel behind the front seat is removed. Therefore, even if the rear seat is raised up behind the front seat as described above, the floor surface of the luggage compartment cannot be expanded.

(Purpose of the invention) The present invention was created in view of the above circumstances, and is an automobile that can expand the cargo compartment floor area by folding down the seat device even in cars equipped with MR engines. The object of the present invention is to provide a seat device.

(Structure of the invention) This invention focuses on the fact that while cars equipped with MR engines require engine space below the rear seat, there is idle space below the front seat. Fold it down and secure it to the front of the passenger compartment, fold down the rear seat and place the front passenger seat in its original position.
At this time, the structure is such that the upper surface of the rear seat is at approximately the same height as the floor panel on which the rear seat was originally placed, thereby increasing the floor surface of the cargo compartment.

That is, in the automobile seat device according to the present invention, a lower section on the front side and an upper section on the rear side are formed in the floor panel, and the passenger front seat is supported on the lower section by fixing means having leg members. Along with being
A seat seat is placed on the upper part, and the passenger front seat has a lower front end of a seat cushion rotatably supported by the fixing means, and a seat back is hinged to the seat cushion. The cushion and the seat back are folded and can be tilted forward as a unit, and when the cushion and the seat back are folded forward, they are fixed to an instrument panel forming the front surface of the vehicle interior via a mounting member, and the rear seat has at least one seat. The cushion can be freely tilted forward, and when the cushion is tilted forward, the back surface of the seat cushion and the upper surface of the upper section are approximately connected to the passenger front seat space formed when the passenger front seat is tilted forward. The fixing means is configured to be arranged at the same height, and the fixing means is provided with support means for avoiding interference with the rear seat and supporting the rear seat in the forward tilted position when the rear seat is tilted forward. It is characterized by the fact that

It may be only the seat cushion of the rear seat that is rotatably arranged in the passenger front seat space, or it may be both the seat cushion and the seat back of the rear seat. In the former case, the seat back that does not rotate functions as a partition between the cargo compartment floor surfaces, and in the latter case, the cargo compartment floor surface can be made into one wide floor. In addition, in either case,
After rotation, the back surface of the seat cushion is at the predetermined height.

(Examples) Examples of the present invention will be described in detail below with reference to the accompanying drawings.
