DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an unlock mechanism for a foldable rear seat back, and in particular, to an unlock mechanism for a foldable rear seat which can be folded forward by releasing a locking device by depressing an unlock knob located on the upper surface of the rear seat back.
BACKGROUND TECHNOLOGY
A conventional unlock mechanism for a foldable rear seat back is disclosed in Japanese Utility Model Application Laid-Open (JP-U) No. 7-18964.
As shown in FIG. 6, in this unlock warning mechanism for a foldable rear seat back, a release lever 100 is moved from a lock position to an unlock position and is held at the unlock position even after a lock lever 102 is moved from an engaged position to a disengaged position. A knob 104A of an operating mechanism 104 is movable between a first operating position (the position shown in FIG. 6) for setting the release lever 100 in the lock position and a second operating position (a position lower than the first operating position) for setting the release lever 100 in the unlock position. In a case in which the knob 104A is moved to the second operating position, an indicator 108 disposed at the upper portion of a rear seat back 106 indicates an unlocked state.
However, with this unlock mechanism for a foldable rear seat back, because the indicator 108 projects at the upper portion of the rear seat back 106, in a case in which the rear seat back 106 is folded forward, the indicator 108 interferes with the seat back of the front seat, and the indicator 108 and the seat back of the front seat may be damaged.
With regard to the technology relating to the present invention, as disclosed in Japanese Utility Model Application Laid-Open (JP-U) No. 6-33729 and Japanese Utility Model Application Laid-Open (JP-U) No. 6-33730, a seat back unlock knob is disposed movably along the longitudinal direction of a vehicle, and when the rear seat back is folded forward and the front seat back is reclined rearward, damage to the front seat back by the unlock knob is prevented.
DISCLOSURE OF THE INVENTION
An object of the present invention is to provide an unlock mechanism for a foldable rear seat back in which damage to an unlocked state indicator and a front seat can be prevented.
The present invention is an unlock mechanism for a foldable rear seat back which can be folded forward by an unlock knob disposed at an upper surface of the rear seat back being pressed so as to release a locking device, said unlock mechanism having a warning mechanism comprising: an unlocked state indicator for indicating an unlocked state of the locking device; urging means for urging said unlocked state indicator so as to cause said unlocked state indicator to protrude from the upper surface of the rear seat back in a case in which the locking device is in an unlocked state; and play means for allowing said unlocked state indicator to be pushed into the rear seat back against urging force of said urging means while maintaining the unlocked state of the locking device in a case in which a load is applied to said unlocked state indicator in a direction of pushing in said unlocked state indicator in a state in which said unlocked state indicator is protruded from the upper surface of the rear seat back.
In this way, when the unlock knob is pressed, the locking device is set in an unlocked state and the rear seat back can be folded forward. At the same time, the urging means causes the unlocked state indicator to protrude from the upper surface of the rear seat back. Further, when the rear seat back is folded forward and the unlocked state indicator interferes with the seat back of the front seat and a load in the direction of pushing the unlocked state indicator in is applied thereto, the unlocked state indicator is pushed into the rear seat back by the play means against the urging force of the urging means. Therefore, the unlocked state indicator and the front seat are prevented from being damaged.
Further, in this case, the lock device may be structured so as to include a latc
