2. Description of the Related Art
Japanese Patent Application laid open under Provisionary Publication No. 2001-301496 discloses three seats for a vehicle, which are arranged side by side and designed in order to facilitate obtaining of a walk-through space in the vehicle. The seats comprise first and second seats, and a center seat arranged between the first and second seats. The center seat includes seat leg means slidably supported to a rail mechanism mounted to a vehicle floor and movable forward and rearward in the vehicle, and a seat cushion pivotally supported to a side of a seat cushion of one of the first and second seats so as to be vertically pivoted and adapted to be carried on the seat leg means and releasably secured with respect to the seat leg means during use of the center seat.
The seat leg means is provided with a striker. The seat cushion is provided with a striker lock. The seat cushion is releasably secured to the seat leg means by causing the striker lock of the seat cushion to be engaged with the striker of the seat leg means.
In the conventional center seat constructed as described above, when it is necessary to obtain a walk-through space in the vehicle, releasing of the seat cushion of the center seat from the seat leg means is carried out by causing the striker lock of the seat cushion to be disengaged from the striker of the seat leg means, whereby the seat cushion is released from the seat leg means. In a condition where the seat cushion of the center seat is released from the seat leg means and pivoted upward by a passenger's hand, when forward or rearward movement of the seat leg means is performed while causing the seat cushion to be released from the passenger's hand, the seat cushion of the center seat is pivoted downward by gravity. Thus, the seat cushion of the center seat is vertically accommodated in a space around the side of the seat cushion of the one of the first and second seats to which the seat cushion of the center seat is pivotally supported, whereby the walk-through space can be provided between the first and second seats. In this condition, the center seat is unavailable.
In the conventional center seat, the seat cushion of the center seat is vertically accommodated in the space around the side of the seat cushion of the one of the first and second seats, so that the walk-through space is provided between the first and second seats as discussed above. However, when the walk-through space is provided between the first and second seats, the seat leg means is located forward or rearward from the first and second seats, so that the seat leg means will interfere with widely utilizing of the space between the first and second seats as a storage space for any longitudinal articles, e.g. umbrellas, and a walk-through space.
Japanese Patent No. 3,356,970 discloses vehicle seats that are designed to be detachable from a vehicle floor in order to facilitate obtaining of a storage space for any longitudinal articles and a walk-through space in a vehicle. In the vehicle seats, there are problems of how each of the detached vehicle seats should be folded or collapsed into a single compact configuration after use of the vehicle seats, of how each of the detached vehicle seats should be easily returned to a usable condition when it is to be used, and of how each of the detached vehicle seats should be stably set on the vehicle floor when it is to be used.
The present invention has been made with a view to overcoming the foregoing problems of the prior art vehicle seats.
It is therefore an object of the present invention to provide a detachable seat for a vehicle, which can be easily folded or collapsed into a single compact configuration after use of the detachable seat, can be easily returned to a usable condition when it is to be used, and can be stably set on a vehicle floor when it is to be used.
It is another object of the present invention to provide a detachable seat for a vehicle, which can be easily detached and stored in a predetermined place in a compactly collapsed or folded condition.
It is still another object of the present invention to provide a detachable seat for a vehicle, which is simply constructed.
In accordance with the present invention, there is provided a detachable seat for a vehicle. The detachable seat comprises a seat cushion, seat leg means for supporting the seat cushion, the seat leg means comprising a base member on which the seat cushion is removably or detachably carried, and first and second spaced apart leg members pivotally connected to the base member so as to be collapsible laterally relative to the base member, a seat back pivotally mounted to the base member of the seat leg means, first cooperating means on the first and second leg members and a vehicle floor for causing an entire seat to be releasably locked with respect to the vehicle floor, and second cooperating means on the base member and the seat cushion for causing the seat cushion to be removably or detachably mounted with respect to the base member.
The first and second leg members are pivotally connected at upper ends thereof to the base member. The seat may further include linkage means for facilitating maintaining of the first and second leg members in standing-up conditions during use of the seat and facilitating laterally collapsing of the first and second leg members after the use of the seat.
The seat may further include first operating means for operating the linkage means, and second operating means for operating the first cooperating means to allow the seat to be released from the vehicle floor. The first and second operating means are provided at the base member so as to be exposed. The first and second operating means are adapted to be concealed by the seat cushion when the seat cushion is carried on the base member.
In a condition where the seat is detached from the vehicle floor and the seat cushion is removed from the base member of the seat leg means, one of the first and second leg members is adapted to be collapsible so as to be laid under the base member, the other of the first and second leg members is adapted to be collapsible so as to project laterally from the base member, the seat cushion is adapted to be carried on the other of the first and second leg members which has projected laterally, and the seat back is adapted to be overlapped on the base member of the seat leg means, whereby the seat is rendered to be a single compact configuration.
The base member of the seat leg means comprises a plate-shaped body having spaced apart rising sections rising from both sides of the plate-shaped body. The seat back has a width narrower than a space between the spaced apart rising sections of the base member, so that when the seat back is overlapped on the base member of the seat leg means, the seat back is received within the space between the spaced apart rising sections of the base member.
The seat further includes a height-adjustable headrest vertically movably supported on the seat back through a headrest stay. The headrest comprises a horizontally extending section and a front side section extending downward from the horizontally extending section for supporting the head of a passenger sitting on the seat. The front side section has a height enough to support the head of the passenger. When the headrest is moved downward relative to the seat back, the horizontally extending section of the headrest is abutted against an upper surface of the seat back and the front side section of the headrest becomes adjacent to a front surface of the seat back. When the seat back is overlapped on the base member of the seat leg means, the headrest is arranged around a front side of the base member of the seat leg means.
The seat cushion comprises a seat cushion body and a downward extending section extending downward from a front side of the seat cushion body. The seat cushion is adapted to be carried on the base member of the seat leg means with the downward extending section of the seat cushion being arranged around the front side of the base member of the seat leg means. In a condition where the seat back is overlapped on the base member of the seat leg means and the seat cushion is carried on the other of the first and second leg members which has been collapsed so as to project laterally from the base member of the seat leg means, the downward extending section of the seat cushion is adapted to be lined up with the headrest.
These and other objects and many of the attendant advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, in which like reference numerals denote the same parts throughout the Figures and wherein:
