Abstract
A memory bracket configured for use in a vehicle seat rail assembly. The rail assembly including a translatable rail provided with a first stop member and the memory bracket fixed to a fixed rail and including a second stop member. In response to the translatable rail being positioned in a use position, the first stop member contacts the second stop member, and as the translatable rail moves in the longitudinal direction from an ingress-egress position to the one or more use positions, a portion of the memory bracket engages and displaces a mechanical effector of an ingress-egress aid to permit the backrest to pivot away from the seating surface.
Claims20
A vehicle seat comprising:
- a rail assembly including a fixed rail, a translatable rail, and a locking device, the locking device configured to operate in a locked state in which the locking device locks the translatable rail to the fixed rail, and an unlocked state, in which the locking device unlocks the translatable rail from the fixed rail to permit translation of the translatable rail along the fixed rail;
- a seat sub-frame fixed to the translatable rail;
- a backrest pivotally connected to the seat sub-frame and configured to pivot towards a seating surface of the seat sub-frame, wherein the translatable rail is configured to carry the seat sub-frame;
- an ingress-egress aid coupled to the backrest and the locking device, wherein in response to the backrest pivoting towards the seat surface, the ingress-egress aid is configured to change the locking device from the locked state to the unlocked state to collectively permit the translatable rail to move along the fixed rail in a first direction to an ingress-egress position;
- and
- a memory ramp fixed to the fixed rail, wherein the ingress-egress aid includes a mechanical effector, wherein as the translatable rail moves in a second direction from the ingress-egress position to one or more use positions, the mechanical effector moves along the memory ramp in the second direction and a vertical direction to permit the backrest to pivot away from the seating surface, and wherein the second direction is substantially opposite to the first direction.
A rail assembly for use in a vehicle seat, the vehicle seat including a seat sub-frame, a backrest pivotally connected to the seat sub-frame and configured to pivot towards a seating surface of the seat sub-frame, and an ingress-egress aid coupled to the backrest, the rail assembly comprising:
- a fixed rail;
- a translatable rail configured to carry the seat sub-frame, wherein the translatable rail includes a first stop member;
- a locking device, the locking device configured to be coupled to the ingress-egress aid, wherein the locking device is further configured to operate in a locked state, in which the locking device locks the translatable rail to the fixed rail, and an unlocked state in which the locking device unlocks the translatable rail from the fixed rail to permit translation of the translatable rail in a longitudinal direction along the fixed rail between one or more use positions to an ingress-egress position, wherein the ingress-egress aid is configured to, responsive to the backrest moving towards the seating surface, change the locking device from the locked state to the unlocked state;
- and
- a memory bracket fixed to the fixed rail and including a second stop member, wherein when the translatable rail is in a use position of one or more use positions, the first stop member contacts the second stop member, and
- wherein as the translatable rail moves in the longitudinal direction from the ingress-egress position to the one or more use positions, a portion of the memory bracket engages and displaces a mechanical effector of the ingress-egress aid to permit the backrest to pivot away from the seating surface.
A vehicle seat comprising:
- a rail assembly including a fixed rail, a translatable rail, and a locking device, wherein the translatable rail includes a first stop member, wherein the locking device is configured to operate in a locked state, in which the locking device locks the translatable rail to the fixed rail, and an unlocked state in which the locking device unlocks the translatable rail from the fixed rail to permit translation of the translatable rail along the fixed rail;
- a seat sub-frame fixed to the translatable rail;
- a backrest pivotally connected to the seat sub-frame and configured to pivot towards a seating surface of the seat sub-frame, wherein the translatable rail is configured to carry the seat sub-frame and the backrest;
- an ingress-egress aid coupled to the backrest and the locking device, wherein in response to the backrest pivoting towards the seat surface, the ingress-egress aid is configured to change the locking device from the locked state to the unlocked state to permit the translatable rail to move along the fixed rail in a first direction from one or more use positions to an ingress-egress position;
- a memory bracket fixed to the fixed rail, wherein the memory bracket forms an inclined plane, wherein a height of the inclined plane increases with respect to a second direction, wherein the second direction is opposite the first direction;
- and
- a second stop member coupled to the memory bracket, wherein when the translatable rail is in a use position of the one or more use positions, the first stop member contacts the second stop member,
- wherein the ingress-egress aid includes a mechanical effector, wherein as the translatable rail moves in the second direction from the ingress-egress position to the one or more use positions, the inclined plane engages and displaces the mechanical effector to permit the backrest to pivot away from the seating surface.
