ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a vehicular seat such as a rear seat for a vehicle.
2. Description of the Related Art
FIGS. 10A
to
10
E are side views of a related vehicular seat. Specifically, a retractable rear seat
100
is shown as one example of a vehicular seat.
In
FIG. 10A
, a seat back
101
of the rear seat
100
, which is in an in-use state, is folded down toward a seat cushion
102
as indicated by an arrow al, and a hook
105
provided on the seat cushion
102
is released from a hook retaining member
104
provided on a floor
103
side.
In
FIG. 10B
, a stay
106
is attached to the floor
103
. A link
107
is rotatably attached to the stay
106
at one end thereof and it is also rotatably attached to a seat cushion
102
side at the other end of thereof. The folded seat
100
is rotated as indicated by an arrow b about the one end of the link
107
, so that it is received in the floor
103
. That is, the rear seat is put in a received state.
In
FIG. 10C
, the rear seat
100
in the received state is lifted up as indicated by an arrow c1 and then pulled as indicated by an arrow c2.
In
FIG. 10D
, the folded rear seat
100
is further lifted up as indicated by an arrow d and then lowered toward the hook retaining member
104
, the hook
105
being hooked on the hook retaining member
104
.
As shown in
FIG. 10C
, since the hook
105
is located below the seat cushion
102
, the hook
105
is hard to be seen by an operator M, and therefore there is caused a risk in which the hook
105
is erroneously judged as being hooked on the hook retaining member
104
when the hook
105
is brought into abutment with the hook retaining member
104
.
In addition, as shown in
FIG. 10D
, in view of the fact that an operation is carried out inside a vehicle (not shown), it is hard work to lift up the folded seat
100
as indicated by the arrow d when the hook
105
is tried to be hooked on the hook retaining member
104
, and therefore it is desired that the hook
105
can be hooked on the hook retaining member
104
without the necessity of lifting up the rear seat
100
.
Moreover, as shown in
FIG. 10E
, since the folded rear seat
100
happens to abruptly spring back as indicated by an arrow c by virtue of the inertia of a vehicle (not shown), a fixing means (not shown) is needed to fix the seat cushion to the floor
103
side in the received state.
However, if a fixing means (not shown) is provided in order to prevent the folded rear seat
100
from springing back, the fixing means has to be released when the folded rear seat is returned from the received state to the in-use state, this providing inconvenience in utilization of the rear seat.
Work to return the folded rear seat
100
from the received state to the in-use state involves work to lift up the folded rear seat
100
, and in view of the fact that such work is carried out inside the vehicle (not shown), it is desired that the rear seat be returned from the received state to the in-use state without carrying out any work such as work to release the fixing means.
SUMMARY OF THE INVENTION
To cope with these problems, it is an object of the present invention to provide a vehicular seat that can securely and easily be fastened to a floor side. Further, it is another object of the present invention to provide a vehicular seat that can automatically prevent the vehicular seat from springing back when it is moved from an in-use state to a received state and which allows the vehicular seat to be returned form the received state to the in-use state without carrying out any operation to release the spring-back prevention mechanism.
With a view to attaining the above object, there is provided a vehicular seat in which a link which is rotatably fixed to a floor is connected to a seat frame at one end thereof for guiding the vehicular seat for movement from an in-use state to a received state and vice versa. The vehicular seat includes a rotation restraining member provided in such a manner as to extend between the floor and the seat frame for restraining the vehicular seat, which has reached the received state from the in-use state, from further rotating about the link by virtue of the action of inertia.
The rotation restraining member is provided so as to extend between the floor and the frame for restraining the vehicular seat by restraining therewith the rotation of the vehicular seat about the one end of the link.
With a view to attaining the another object, there is provided a vehicular seat including a link connecting a seat frame to a floor and adapted to be guided by said link so as to be moved from an in-use state to a received state and vice versa after a hook on a seat frame side is separated from locking means on a floor side, wherein an inclined surface is provided on the floor side which allows a lower end of the hook to be matched substantially to the height of an upper surface of the locking means when the vehicular seat is returned from a received state to an in-use state.
In returning the vehicular seat from the received state back to the in-use state, when the hook is slid at a lower end thereof along the inclined surface, pulled up to just before the locking means, and further pulled rearward, the vehicular seat is allowed to be lowered by its own weight, whereby the hook is hooked on the locking means.
When the hook is hooked on the locking means, since the vehicular seat does not have to be lifted up and then lowered, the locking means is easily be hooked by the hook. In addition, since the vehicular seat only has to be pulled rearward to be hooked on the locking means, the hook can securely be hooked on the locking means.
