Definitions
- the present invention relates to a vehicle seat.
- Patent Document 1 discloses a vehicle seat that moves backward and downward with respect to the floor and is stored in a storage recess formed in the floor.
- a vehicle seat has a support leg rotatably connected to a floor, a seat cushion rotatably supported by the support leg, and a coupling device detachably coupled to a striker provided on the floor. Rotation of the support legs moves the vehicle seat between the use position and the stowed position.
- a coupling device couples to the striker to maintain the vehicle seat in the position of use.
- a user can sit on the vehicle seat according to Patent Document 1 only when it is in the use position. If the vehicle seat has a plurality of seating configurations, the commercial value of the vehicle seat is enhanced.
- an object of the present invention is to provide a vehicle seat having a plurality of seating configurations.
- the present invention provides a vehicle seat (1) comprising a support leg (6) rotatably connected to a vehicle body about a first axis (A1) extending in a horizontal direction, A seat cushion (2) rotatably connected to the support leg about a second axis (A2) parallel to the first axis; and a first coupling portion provided on the support leg and provided on the vehicle body.
- the seat cushion has a storage position at the lowest position, a first use position in which the first coupling device is coupled to the first coupling portion, and a second coupling device to the second coupling portion. It is movable between a second use position coupled to the part.
- the seat cushion is arranged in the first use position and the second use position in addition to the storage position, the seat arrangement that can be selected by the user increases.
- the seat cushion in the second use position is arranged above the seat cushion in the retracted position, and the seat cushion in the first use position is arranged in the second use position. It may be arranged above a certain seat cushion.
- the height and front-back position of the seat cushion change.
- the vehicle body has a floor (4), and the floor comprises a front floor portion (4A), an intermediate floor portion (4B) extending downward from the rear end of the front floor portion, and an intermediate floor portion (4B) extending downward from the rear end of the front floor portion. and a floor rear portion (4C) extending rearward from the lower end of the floor and disposed below the floor front portion, and the lower ends of the support legs are rotatable around the first axis extending laterally to the floor rear portion.
- the first connecting portion is provided in the middle portion of the floor, the majority of the seat cushion is disposed above the rear portion of the floor in the stowed position, and the front portion of the floor in the first use position. It may be arranged above.
- the seat cushion in the storage position, can be arranged on the rear portion of the floor that is recessed downward with respect to the front portion of the floor.
- the second coupling portion may be provided at the rear end portion of the floor front portion or the upper end portion of the floor intermediate portion.
- the distance between the seat cushion and the second coupling portion is shortened, so the stability of the seat cushion is improved.
- the seat cushion has a base member (10) connected to the support leg and an upper member (12) supported by the base member, and the second coupling device is attached to the base member. It may be movable in the front-rear direction.
- the seating position can be moved back and forth between the first use position and the second use position.
- the upper member may be movably supported by the base member in the front-rear direction via a slide device (11), and the second coupling device may be provided on the upper member.
- the second connecting portion can be moved back and forth together with the seat cushion.
- the second coupling device when the second coupling device is in the predetermined coupling position with respect to the base member and the seat cushion is in the second use position, the second coupling device is connected to the second coupling portion. and the second coupling device may not be coupled to the second coupling portion when the second coupling device is not in the coupling position and the seat cushion is in the second use position.
- the upper surface of the seat cushion when the seat cushion is in the retracted position, the upper surface of the seat cushion is positioned below the upper surface of the front floor portion, and when the seat cushion is in the second use position, The upper surface of the seat cushion may be positioned above the upper surface of the front floor portion.
- the seat cushion can be arranged below the front portion of the floor in the retracted position.
- a vehicle seat (1) comprising a support leg (6) rotatably connected to a vehicle body about a horizontally extending first axis (A1) and a support leg (6) parallel to the first axis.
- a seat cushion (2) rotatably connected to the support leg about a second axis (A1); a first coupling device (35) to be coupled, and a second coupling device (38) provided on the seat cushion and detachably coupled to a second coupling portion (37) provided on the vehicle body;
- the seat cushion has a stored position at the lowest position, a first use position where the first coupling device is coupled to the first coupling portion, and a second use position where the second coupling device is coupled to the second coupling portion.
- the first coupling portion and the second coupling portion are provided adjacent to each other.
- the vehicle seat having a plurality of seating configurations. Since the seat cushion is arranged in the first use position and the second use position in addition to the storage position, the seat arrangement that can be selected by the user increases.

Abstract
Description
第1縁部319がループ部材313に縫製等によって連結されているため、吊り込み部材315がループ部材313及び吊り込み縁部312対してずれず、吊り込み溝311の正しい位置に吊り込み縁部312を取り付けることができる。特に、縫製ライン322が長手方向に連続する場合は、吊り込み部材315がループ部材313に対して長手方向に更にずれ難くなる。
