The second brace is spaced from the first brace by a gap including a gap axis that is parallel to each of the first brace and the second brace. The first brace arm includes a first brace surface that is selectively shiftable toward the gap axis to engage a first wheel of the wheelchair, and the second brace arm includes a second brace surface that is selectively shiftable toward the gap axis to engage a second wheel of the wheelchair. ## Claims ### Claim 1 A wheelchair docking station for a wheelchair in a vehicle, the wheelchair docking station comprising: a first brace including a first brace arm, the first brace being mountable in the vehicle; a second brace including a second brace arm, the second brace being mountable in the vehicle, the second brace being spaced from the first brace by a gap including a gap axis that is parallel to each of the first brace and the second brace; wherein the first brace arm includes a first brace surface that is selectively shiftable toward the gap axis to engage a first wheel of the wheelchair and is operatively connected to a first support surface on a first side of the gap axis, and a first clamping mechanism is mounted at the first support surface and coupled to the first brace surface; wherein the second brace arm includes a second brace surface that is selectively shiftable toward the gap axis to engage a second wheel of the wheelchair and is operatively connected to a second support surface on a second side of the gap axis, and a second clamping mechanism is mounted at the second support surface and connected to the second brace surface; and a docking actuator connected to the first clamping mechanism and the second clamping mechanism, the docking actuator being operable to shift the first brace surface toward the first wheel and the second brace arm toward the second wheel, wherein the docking actuator includes a first motor operatively connected to the first brace arm and a second motor operatively connected to the second brace arm, the first motor including a first axle supporting a first drive member and the second motor including a second axle supporting a second drive member, the first motor being operable to shift the first brace arm across the first support surface and the second motor being operable to shift the second brace arm across the second support surface. ### Claim 2 (depends on 1) The wheelchair docking station according to claim 1, wherein the first axle extends substantially parallel to the gap axis and includes a first end and a second end opposite the first end, the first drive member including a first gear mounted to the first end and a second gear mounted to the second end and the second axle extends substantially parallel to the gap axis and includes a first end portion and a second end portion opposite the first end portion, the second drive member including a third gear mounted to the first end portion and a fourth gear mounted to the second end portion. ### Claim 3 (depends on 2) The wheelchair docking station according to claim 2, further comprising a sensor coupled to the first motor, the sensor detecting a parameter of the first motor associated with pressure being applied to the first wheel by the first brace surface. ### Claim 4 (depends on 1) The wheelchair docking station according to claim 1, wherein the first clamping mechanism includes a first selectively inflatable member mounted to the first brace arm and defining the first brace surface and the second clamping mechanism includes a second selectively inflatable member mounted to the second brace arm and defining the second brace surface. ### Claim 5 (depends on 4) The wheelchair docking station according to claim 4, wherein the docking actuator comprises a pump fluidically connected to at least one of the first selectively inflatable member and the second selectively inflatable member. ### Claim 6 (depends on 1) The wheelchair docking station according to claim 1, further comprising a docking controller operatively connected to docking mechanism, the docking controller controlling movement of the first brace surface and the second brace surface. ### Claim 7 (depends on 1) The wheelchair docking station according to claim 1, further comprising a seating motor operatively connected to the first support surface and the second support surface, the seating motor selectively shifting the first support surface and the second support surface along the gap axis. ### Claim 8 A vehicle comprising: a body including a passenger compartment having a floor; and a wheelchair docking station arranged in the passenger compartment, the wheelchair docking station comprising: a first brace including a first brace arm, the first brace being mounted to the floor; a second brace including a second brace arm, the second brace being mounted to the floor, the second brace being spaced from the first brace by a gap including a gap axis that is parallel to each of the first brace and the second brace; wherein the first brace arm includes a first brace surface that is selectively shiftable toward the gap axis to engage a first wheel of a wheelchair and is operatively connected to a first support surface on a first side of the gap axis, and a first clamping mechanism is mounted at the first support surface and coupled to the first brace surface; wherein the second brace arm includes a second brace surface that is selectively shiftable toward the gap axis to engage a second wheel of the wheelchair and is operatively connected to a second support surface on a second side of the gap axis that is opposite the first side, and a second clamping mechanism is mounted at the second support surface and connected to the second brace surface; and a docking actuator connected to the first clamping mechanism and the second clamping mechanism, the docking actuator being operable to shift the first brace surface toward the first wheel and the second brace arm toward the second wheel, wherein the docking actuator includes a first motor operatively connected to the first brace arm and a second motor operatively connected to the second brace arm, the first motor including a first axle supporting a first drive member and the second motor including a second axle supporting a second drive member, the first motor being operable to shift the first brace arm across the first support surface and the second motor being operable to shift the second brace arm across the second support surface. ### Claim 9 (depends on 8) The vehicle according to claim 8, wherein the first axle extends substantially parallel to the gap axis and includes a first end and a second end opposite the first end, the first drive member including a first gear mounted to the first end and a second gear mounted to the second end and the second axle extends substantially parallel to the gap axis and includes a first end portion and a second end portion opposite the first end portion, the second drive member including a third gear mounted to the first end portion and a fourth gear mounted to the second end portion. ### Claim 10 (depends on 9) The vehicle according to claim 9, further comprising a sensor coupled to the first motor, the sensor detecting a parameter of the first motor associated with pressure being applied to the first wheel by the first brace surface. ### Claim 11 (depends on 8) The vehicle according to claim 8, wherein the first clamping mechanism includes a first selectively inflatable member mounted to the first brace arm and defining the first brace surface and the second clamping mechanism includes a second selectively inflatable member mounted to the second brace arm and defining the second brace surface. ### Claim 12 (depends on 11) The vehicle according to claim 11, wherein the docking actuator comprises a pump fluidically connected to at least one of the first selectively inflatable member and the second selectively inflatable member. ### Claim 13 (depends on 8) The vehicle according to claim 8, further comprising a docking controller operatively connected to docking mechanism, the docking controller controlling movement of the first brace surface and the second brace surface. ### Claim 14 (depends on 8) The vehicle according to claim 8, further comprising a seating motor operatively connected to the first support surface and the second support surface, the seating motor selectively shifting the first support surface and the second support surface along the gap axis.
