The sliding door includes a pin, which is slideably attached to the door, slideable between a pin retracted position and a pin extended position, a tip of the pin interacting with the attenuation and retraction device. The door further includes a wheel carried by a wheel holder, which is arranged to move the wheel between a wheel retracted position and a wheel extended position. A transmission mechanism interconnects the wheel holder and the pin such that a movement of the wheel, towards the wheel extended position, urges the pin towards the pin extended position. ## Claims ### Claim 1 A sliding door for use with a rail system having a rail for guiding a sliding motion of the door and an attenuation and retraction device for braking the sliding motion of the door at a brake position in proximate a door end position and retracting the door to the end position, comprising: a pin attached to the door and slideable between a pin retracted position and a pin extended position, the pin having a pin tip for interacting with the attenuation and retraction device; and a wheel carried by a wheel holder for moving the wheel between a wheel retracted position and a wheel extended position, the wheel holder including a transmission mechanism interconnecting the wheel holder and the pin for urging the pin towards the pin extended position in response to movement of the wheel towards the wheel extended position. ### Claim 2 (depends on 1) The sliding door of claim 1, wherein the wheel holder comprises a spring for urging the wheel towards a wheel extended position against the rail. ### Claim 3 (depends on 1) The sliding door of claim 1, wherein the transmission mechanism is operable to maintain a gap between the pin tip and the rail. ### Claim 4 (depends on 3) The sliding door of claim 3, wherein the maintained gap is in the range 2±0.5 mm. ### Claim 5 (depends on 1) The sliding door of claim 1, further comprising a spring for urging the pin towards the pin retracted position. ### Claim 6 (depends on 1) The sliding door of claim 1, wherein the transmission mechanism comprises: a transmission lever pivotably suspended at a pivot axis, the transmission lever having a first arm and a second arm, the first arm disposed at a side of the pivot axis opposite the second arm; an abutment disposed on the wheel holder for moving the first arm of the transmission lever such that the second arm of the transmission lever moves the pin toward the pin extended position through contact on a pin abutment surface. ### Claim 7 (depends on 1) The sliding door of claim 1, wherein the pin comprises: a pin wing; and a pin waist narrower than the pin wing and spaced from the pin tip by the pin wing, wherein the pin wing is adapted to catch the attenuation and retraction device for pulling the pin from the pin retracted position. ### Claim 8 (depends on 1) The sliding door of claim 1, wherein the wheel holder and the pin are mounted in a cassette. ### Claim 9 (depends on 2) The sliding door of claim 2, further comprising a spring for urging the pin towards the pin retracted position. ### Claim 10 (depends on 3) The sliding door of claim 3, further comprising a spring for urging the pin towards the pin retracted position. ### Claim 11 (depends on 2) The sliding door of claim 2, wherein the transmission mechanism comprises: a transmission lever pivotably suspended at a pivot axis and having a first arm and a second arm, the first and the second arms disposed on opposite sides of the pivot axis; an abutment disposed on the wheel holder for moving the first arm of the transmission lever such that the second arm of the transmission lever moves the pin through contact on a pin abutment surface. ### Claim 12 (depends on 3) The sliding door of claim 3, wherein the transmission mechanism comprises: a transmission lever pivotably suspended at a pivot axis and having a first arm and a second arm, the first and the second arms disposed on opposite sides of the pivot axis; an abutment disposed on the wheel holder for moving the first arm of the transmission lever such that the second arm of the transmission lever moves the pin through contact on a pin abutment surface. ### Claim 13 (depends on 5) The sliding door of claim 5 wherein the transmission mechanism comprises: a transmission lever pivotably suspended at a pivot axis and having a first arm and a second arm, the first and the second arms disposed on opposite sides of the pivot axis; an abutment disposed on the wheel holder for moving the first arm of the transmission lever such that the second arm of the transmission lever moves the pin through contact on a pin abutment surface. ### Claim 14 (depends on 2) The sliding door of claim 2, wherein the pin comprises: a pin wing; and a pin waist narrower than the pin wing and spaced from the pin tip by the pin wing, wherein the pin wing is adapted to catch the attenuation and retraction device for pulling the pin from the pin retracted position. ### Claim 15 (depends on 3) The sliding door of claim 3, wherein the pin comprises: a pin wing; and a pin waist narrower than the pin wing and spaced from the pin tip by the pin wing, wherein the pin wing is adapted to catch the attenuation and retraction device for pulling the pin from the pin retracted position. ### Claim 16 (depends on 5) The sliding door of claim 5, wherein the pin comprises: a pin wing; and a pin waist narrower than the pin wing and spaced from the pin tip by the pin wing, wherein the pin wing is adapted to catch the attenuation and retraction device for pulling the pin from the pin retracted position. ### Claim 17 (depends on 6) The sliding door of claim 6, wherein the pin comprises: a pin wing; and a pin waist narrower than the pin wing and spaced from the pin tip by the pin wing, wherein the pin wing is adapted to catch the attenuation and retraction device for pulling the pin from the pin retracted position. ### Claim 18 (depends on 2) The sliding door of claim 2, wherein the wheel holder and the pin are mounted in a cassette. ### Claim 19 (depends on 3) The sliding door of claim 3, wherein the wheel holder and the pin are mounted in a cassette. ### Claim 20 (depends on 5) The sliding door of claim 5, wherein the wheel holder and the pin are mounted in a cassette. ### Claim 21 (depends on 6) The sliding door of claim 6, wherein the wheel holder and the pin are mounted in a cassette. ### Claim 22 (depends on 7) The sliding door of claim 7, wherein the wheel holder and the pin are mounted in a cassette.
