Problems solved by technology

However, if this is the case, there is no seat surface angle that is most suitable for both large occupants and small occupants. Regardless of the occupant, it is easy to become a structure that deteriorates the seating performance.

Embodiment 1

[0071] The connecting mechanism of this embodiment has a first link arm 11, a second link arm 12, and a plurality of brackets BR1 to BR4 (refer to figure 1 and figure 2 ).

[0072] Both the first link arm 11 and the second link arm 12 are I-shaped (in side view) flat plate members, and can be disposed between the seat cushion 4 and the floor surface FS. Furthermore, the plurality of brackets BR1 to BR4 are members (typically, flat plate materials) to which the ends of the link arms can be rotatably attached.

[0073] In this embodiment, a first bracket BR1 protrudes downward from the rear front end of the seat cushion 4 , and a second bracket BR2 protrudes downward from the rear rear end of the seat cushion 4 .

[0074] In addition, the third bracket BR3 protrudes upward on the floor surface FS, and is arranged so as to face the front portion of the seat cushion 4 (first bracket BR1 ) in the first state. Further, the fourth bracket BR4 is protruded upward on the floor surf...

Embodiment 2

[0105] Since the vehicle seat 2A of the present embodiment has substantially the same basic structure as the vehicle seat 2 of the first embodiment, corresponding symbols and the like are assigned to common structures, and detailed description thereof will be omitted.

[0106] The connecting mechanism of this embodiment has the arm portion 20 of the seat cushion 4 and the bracket BR5 (refer to image 3 and Figure 4 ).

[0107] The arm portion 20 is a flat portion (approximately I-shaped in side view) and extends from the substantially center of the rear surface of the seat cushion 4 (seat frame 4F) toward the floor surface FS side. Furthermore, the bracket BR5 is a flat plate member protrudingly provided on the floor surface FS, and can attach the end part of the arm part 20 freely.

[0108] In this embodiment, the front side of the seat cushion 4 is arranged slightly above the rear side, and the seat structural members are arranged at the positions in the first state. At ...

Embodiment 3

[0113] The vehicle seat 2B of the present embodiment has substantially the same basic structure as the vehicle seat 2 of the first embodiment, and therefore the common structures are denoted by corresponding symbols or the like, and detailed description thereof will be omitted.

[0114] The connecting mechanism of the present embodiment has upper rail 31, lower rail 32, base 34 (refer to Figure 5 ). The lower rail 32 is a flat plate member whose upper side is arc-shaped (convex shape when viewed from the side), and whose front side gradually curves downward and the rear side gradually curves downward with a substantially central apex as a boundary. Furthermore, the upper rail 31 is a flat plate member that can be slidably assembled to the lower rail 32 , and its lower side has an arc shape (concave surface shape in side view) that follows the lower rail 32 .

[0115] In this embodiment, the lower rail 32 is fixed to the floor surface FS via the base 34, and the upper rail 31...

Abstract

A vehicle seat that changes the seat surface angle of the seat cushion with high performance in response to the state displacement of the vehicle seat. The seat surface of the seat cushion (4) in the first state is brought into a state of gradually tilting upward from the rear of the seat toward the front of the seat, and the connecting mechanism displaces the seat cushion (4) to the second state. And the front side of the seat cushion (4) is moved downward than in the first state, so that the seat surface of the seat cushion (4) in the second state is closer to a horizontal state than in the first state.

Description

technical field [0001] The present invention relates to a vehicle seat capable of moving in a vehicle interior. Background technique [0002] As such a vehicle seat, a vehicle seat including a seat cushion, a seat back rising from the seat cushion, and a connecting mechanism (seat rail, slide rail) is known (see Patent Document 1). . [0003] In the known technique, the seat rail is provided on the floor surface on the rear side of the instrument panel, and is extended along the front-rear direction of the vehicle interior. In this state, by assembling the slide rail at the lower part of the seat cushion to the seat rail, the vehicle seat faces the instrument panel and is provided so as to be slidable on the floor surface. In addition, in the case of a large occupant, the vehicle seat is slid to the rear side away from the instrument panel. Furthermore, in the case of a small occupant, the vehicle seat is slid forward to approach the dashboard. [0004] However, in such ...
