Seat adjustment mechanism for a vehicle seat, and vehicle seat
A seat adjustment mechanism for a vehicle seat is provided. The mechanism may have a number of first pairs of rails, where each first pair of rails has an upper rail and a lower rail. The mechanism may also have a number of second pairs of rails with a substantially same acting direction as the number of first pairs of the pairs.
1. A seat adjustment mechanism for a vehicle seat, comprising a number of first rail pairs, each first rail pair comprising an upper rail and a lower rail, wherein a number of second rail pairs have a substantially identical direction of action to the number of first rail pairs, and wherein the lower rails of the number of first upper rail pairs are fixed on the upper side to a connecting element and upper rails of the number of second lower rail pairs are fixed on the lower side to the connecting element and at least one motor is arranged on the connecting element, wherein upon movement of said upper rails of said lower rail pairs, said at least one motor and said connecting element are adapted to move with said upper rails of said lower rail pairs.
2. The seat adjustment mechanism as claimed in claim 1 , wherein a connecting element is arranged between the number of first rail pairs and the number of second rail pairs.
3. The seat adjustment mechanism as claimed in claim 2 , wherein the connecting element is single-piece or multiple-piece.
4. The seat adjustment mechanism as claimed in claim 2 , wherein the connecting element is a motor bridge.
5. The seat adjustment mechanism as claimed in claim 2 , wherein the lower rails of the number of first rail pairs are fastened on the upper side to the connecting element, and upper rails of the number of second rail pairs are fastened on the lower side to the connecting element.
6. The seat adjustment mechanism as claimed in claim 1 , wherein a first motor is arranged for electrically driving the number of first rail pairs, and in that a second motor is arranged for electrically driving the number of second rail pairs.
7. The seat adjustment mechanism as claimed in claim 1 , wherein the first motor is arranged on the upper side on the connecting element, and in that the second motor is arranged on the lower side on the connecting element.
8. The seat adjustment mechanism as claimed in claim 1 , wherein holders for receiving in each case one pivoting lever are arranged at ends of the upper rails of the number of first rail pairs.
9. A seat adjustment mechanism for a vehicle seat, comprising:
a number of first rail pairs, each first rail pair comprising an upper rail and a lower rail,
wherein a number of second rail pairs have a substantially identical direction of action to the number of first rail pairs,
wherein the lower rails of the number of first upper rail pairs are fixed on an upper side to a connecting element and upper rails of the number of second lower rail pairs are fixed on a lower side to the connecting element and at least one first motor is connected to a first side of a connecting element,
said at least one first motor is adapted to move said upper rails of said first upper rail pairs, and at least one second motor is connected to a second, opposite side of said connecting element, said at least one second motor is adapted to move said upper rails of said second lower rail pairs, wherein said at least one second motor is connected to said connecting element in such a way that upon movement of said upper rails of said lower rail pairs, said at least one second motor and said connecting element are adapted to move with said upper rails of said lower rail pairs.
