Vehicle seat having folding mechanism
First Claim
1. A vehicle seat having a folding mechanism, the vehicle seat being both fixable and slidable forward and backward relative to the vehicle, the vehicle seat comprising:
- locking means for allowing or preventing seat sliding when unlocked or locked respectively;
a wire joined to the locking means at one end thereof, the wire unlocking or locking the locking means when pulled or at rest respectively;
a base member disposed above the locking means;
a first actuating member, supported to be rotatable in a first direction and a second direction on the base member;
a second actuating member, rotatably supported on the base member coaxially with the first actuating member and joined to another end of the wire, the second actuating member allowing the wire to be at rest when in a first position and pulling the wire when rotated by the first actuating member to be in a second position when the first actuating member is rotated in the second direction;
first urging means for urging the first actuating member in the second direction, disposed between the first actuating member and the second actuating member;
second urging means for urging the second actuating member in the first direction, disposed between the base member and the second actuating member;
an upper member rotatably supported on the base member; and
an engaging projection member rotating integrally with the upper member, the engaging projection member contactable with the first actuating member to rotate the first actuating member in the first direction or the second direction.

Abstract
A vehicle seat having a folding mechanism is comprised of a locking mechanism allowing or preventing seat sliding, a wire joined to the locking mechanism, unlocking or locking the locking mechanism when pulled or at rest respectively, a base member disposed above the locking mechanism, a first actuating member, rotatably supported on the base member, a second actuating member, rotatably supported on the base member coaxially with the first actuating member and joined to another end of the wire, allowing the wire to be at rest when in a forward position and pulling the wire when rotated by the first actuating member to a backward position when the first actuating member is rotated backward, an upper member rotatably supported on the base member, and an engaging projection member which is contactable with the first actuating member to rotate the first actuating member backward or forward.

first urging means for urging the first actuating member in the second direction, disposed between the first actuating member and the second actuating member;
second urging means for urging the second actuating member in the first direction, disposed between the base member and the second actuating member;
an upper member rotatably supported on the base member; and
an engaging projection member rotating integrally with the upper member, the engaging projection member contactable with the first actuating member to rotate the first actuating member in the first direction or the second direction. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A vehicle seat having a folding mechanism, the vehicle seat being both fixable and slidable forward and backward relative to the vehicle, the vehicle seat comprising:
-
locking means for allowing or preventing seat sliding when unlocked or locked respectively;
a wire joined to the locking means at one end thereof, the wire unlocking or locking the locking means when pulled or at rest respectively;
a base member disposed above the locking means;
bottom actuating means for pulling the wire, rotatably supported on the base member and joined to another end of the wire, the bottom actuating means allowing the wire to be at rest when in a first position and pulling the wire when in a second position;
top actuating means for rotating the bottom actuating means from the first position to the second position, rotatably supported on the base member coaxially with the bottom actuating means;
an upper member rotatably supported on the base member; and
an engaging projection member rotating integrally with the upper member, the engaging projection member being in one of a first area, a second area, a third area, and a fourth area, in the first area, the engaging projection member not contacting the top actuating means and the upper member being in a backward folding direction where it is possible to rotate the top actuating means in a second direction when the upper member is rotated in a forward folding direction, in the second area, the engaging projection member pushing and rotating the top actuating means in the second direction and thereby causing the bottom actuating means to be in the second position, in the third area, the engaging projection member not contacting the top actuating means and the upper member being in a forward folding direction where it is possible to rotate the top actuating means in a first direction when the upper member is rotated in a backward folding direction, in the fourth area, the engaging projection member pushing and rotating the top actuating means in the first direction. - View Dependent Claims (16, 17, 18, 19)

20. A vehicle seat comprising:
-
a seat cushion;
a seat back swingably connected above the seat cushion;
a seat slide mechanism disposed between the seat cushion and a floor of a vehicle, the seat slide mechanism being capable of allowing the seat cushion to slide in the fore-and-aft direction of the vehicle; and
a lock mechanism putting the seat slide mechanism in a release state of allowing sliding movement of the seat cushion when the seat back is folded forward at a first angle within a first angle range, the lock mechanism putting the seat slide mechanism in a lock state of prohibiting the sliding movement of the seat cushion when the seat back is folded forward at a second angle within a second angle range greater than the first angle range relative to the seat back before folding forward.
