Abstract
A seat rail locking device for a vehicle includes a lower rail having a plurality of locking grooves formed in an inner flange and opened downward, a locking plate having a plurality of locking teeth configured to be inserted into or withdrawn from the plurality of locking grooves when the locking plate moves upward or downward, an upper rail inserted into the lower rail so as to be slidable straight and having a locking-lifting mechanism configured to switch a locking state by moving the locking plate upward or downward, and an anti-rotation mechanism configured to suppress a rotation of the locking plate against a transverse load applied to the upper rail.
Claims13
A seat rail locking device for a vehicle, the seat rail locking device comprising:
- a lower rail having a plurality of locking grooves defined in an inner flange and opened downward;
- a locking plate having a plurality of locking teeth configured to be inserted into or withdrawn from the plurality of locking grooves when the locking plate moves upward or downward;
- an upper rail configured to be inserted into the lower rail to be slidably disposed thereon and having a locking-lifting mechanism configured to switch a locking state by moving the locking plate upward or downward;
- and
- an anti-rotation mechanism configured to suppress a rotation of the locking plate against a transverse load applied to the upper rail,
- wherein the anti-rotation mechanism comprises a plurality of catching protrusions disposed on at least one of the plurality of locking teeth of the locking plate.
A seat rail locking device for a vehicle, the seat rail locking device comprising:
- a lower rail having a plurality of locking grooves;
- an upper rail configured to be inserted into the lower rail to be slidably disposed thereon;
- a locking plate configured to be inserted into or withdrawn from the plurality of locking grooves of the lower rail by moving upward or downward relative to the upper rail;
- a spring configured to elastically support the locking plate upward and allow a plurality of locking teeth of the locking plate to be inserted into the plurality of locking grooves of the lower rail;
- and
- a center pin configured to implement a state in which the plurality of locking teeth are withdrawn from the plurality of locking grooves by moving the locking plate downward while overcoming an elastic force of the spring by means of a straight displacement provided from an outside,
- wherein a plurality of catching protrusions are disposed on at least one of the plurality of locking teeth of the locking plate to prevent a rotation and withdrawal of the locking plate relative to the lower rail,
- wherein the locking plate comprises a central portion disposed at a center thereof and extending in a longitudinal direction of the upper rail, and the plurality of locking teeth protrude from two opposite sides of the central portion to be correspondingly inserted into the plurality of locking grooves of the lower rail, and
- wherein in the locking plate, a first set of the catching protrusions protrude forward from the locking teeth, which are positioned at a front side of one side of the central portion, and a second set of the catching protrusions protrude rearward from the locking teeth, which are positioned at a rear side of another side of the central portion.
A seat rail locking device for a vehicle, the seat rail locking device comprising:
- a central portion having a flat plate shape and extending straight;
- a plurality of locking teeth protruding from two opposite sides of the central portion in a direction perpendicular to a longitudinal direction of the central portion and disposed at predetermined intervals;
- and
- catching protrusions protruding from ends of at least one of the plurality of locking teeth in the longitudinal direction of the central portion.
