The present disclosure relates to a leg rest release mechanism () for a wheelchair, wherein the leg rest release mechanism () comprises: a base member () having a base portion () and an elongated axle portion () extending from the base portion (), a leg rest swivel frame () in swivel connection with the axle portion () to enable swivelling of the leg rest swivel frame () relative to the axle portion (), wherein the leg rest swivel frame () is configured to be connected to an elongated foot rest mounting member () provided with a foot rest (), and a release member () having a lifting handle (), wherein the release member () extends through the leg rest swivel frame () and wherein the release member () is biased to engage with the base portion () to thereby lock the leg rest swivel frame () in a fixed position relative to the base member (), wherein the release member () is configured to disengage from the base portion () by pulling of the lifting handle (), whereby the leg rest swivel frame () is enabled to swivel relative to the base member ().

Leg rest release mechanism and wheelchair comprising the same

The present disclosure relates to a wheelchair () with tilt capabilities. The electric wheelchair comprises a chassis (), a lift device having a base member which is fixedly arranged to the chassis, and a lifting member arranged to move rectilinearly relative to the base member along an axis defined by a longitudinal extension of the lifting member, a tilt frame, a first arm pivotally coupled to the lifting member and the tilt frame, and a second arm coupled to the base member, and which second arm is pivotally coupled to the first arm forming a pivot connection, wherein movement of the lifting member towards the extended position moves the pivot connection towards the base member and movement of the lifting member towards the retracted position moves the pivot connection away from the base member.

Wheelchair with tilt capability

The invention concerns a seat tilt apparatus () for an electric wheelchair, which wheelchair comprises a chassis () and a seat (). The seat tilt apparatus comprises; a base member (), which is fixable to the chassis and provided with at least one first guide slot (); a seat supporting member () which is arranged to supportably receive the seat, movable in relation to the base member and guided by the first guide slot; and a linear drive means () which is connected to the base member and to the seat supporting member, for moving the seat supporting member along a motion path, in relation to the base member. The seat supporting member comprises at least one first cam surface () facing in a first direction; and the base member comprises at least one first rotational support member (), said first cam surface being arranged to be in supporting contact with said first rotational support member and formed for altering the angle between the seat supporting member and the base member during movement along a first interval of said motion path. The invention also concerns an electric wheelchair provided with such a seat tilt apparatus.
