Abstract
An adequate mechanical stiffness and strength are afforded to a tumble seat or a vehicle seat having a latch mechanism provided in a rear end of the seat cushion. A cushion frame (F1) of the seat includes a side frame (5) extending in a fore and aft direction, and the side frame includes a first member (10) comprising a channel member having an open side facing sideways and a second member (11) attached to the first member so as to form a closed cross section jointly with the first member, and extending downward further than the first member. A latch mechanism is positioned under the first member and attached to the second member.
Claims13
A vehicle seat comprising:
- a seat cushion frame comprising a front part pivotally supported by a floor and a rear part fitted with a latch mechanism adapted to be detachably engaged by a striker attached to the floor,
- wherein the seat cushion frame comprises a pair of side frames extending in a fore and an aft direction on either side of the seat cushion frame, a front frame connecting front ends of the pair of side frames to each other, and a rear frame connecting rear ends of the pair of side frames to each other,
- each side frame of the pair of side frames is respectively rotatably connected to a support base of a pair of support bases around a rotational center line extending laterally, the pair of support bases being fixedly attached to the floor,
- at least one of the pair of side frames includes a first member comprising a channel member having an open side facing sideways and a second member attached to the first member so as to be located on an inner side of the first member, and extending downward further than the first member,
- the latch mechanism being positioned under the first member and attached to the second member, and
- one of the pair of support bases is located on an outer side of the first member and is located on an outer side of the latch mechanism.
A method for making a vehicle seat, the vehicle seat including a seat cushion frame having a front part pivotally supported by a floor and a rear part fitted with a latch mechanism adapted to be detachably engaged by a striker attached to the floor, the method comprising:
- forming the seat cushion frame comprising a pair of side frames extending in a fore and an aft direction on either side of the seat cushion frame, a front frame connecting front ends of the pair of side frames to each other, and a rear frame connecting rear ends of the pair of side frames to each other, at least one of the pair of side frames including a first member comprising a channel member having an open side facing sideways and a second member attached to the first member so as to be located on an inner side of the first member, and extending downward further than the first member,
- attaching the latch mechanism to the second member so as to be positioned under the first member, and
- pivotally supporting the front part of the seat cushion frame around a rotational center line extending in the lateral direction by a pair of support bases projecting upward from a floor, the pair of support bases being fixedly attached to the floor,
- wherein one of the pair of support bases is located on an outer side of the first member and is located on an outer side of the latch mechanism.
