Abstract

A retractable handle arrangement comprising a handle movable between stowed, deployed and operative states, and including first and second deployment means both of which are operable independently to move the handle from the stowed state to the deployed state. The first deployment mechanism is electrically actuated and the second deployment mechanism is manually actuated. The second deployment mechanism is a two-state latching mechanism, which may be a so-called ‘push-push’ mechanism, operable to deploy the handle when triggered by a small inward movement.

Claims

1. A retractable handle arrangement comprising a handle movable between stowed, deployed and operative states, and including first and second deployment mechanisms both of which are operable independently to move the handle from the stowed state to the deployed state wherein the first deployment mechanism is electrically actuated, and wherein the handle comprises a handle loop and the second deployment mechanism is a manually actuated two-state latching mechanism operable between a compressed state and an extended state;

wherein in transitioning from the compressed state to the extended state, the latching mechanism is arranged to bear against a support structure and exert a force on the handle to urge the handle into the deployed state, and wherein the latching mechanism is located on an inboard side of an inner member of the handle loop and extends away from the inner member so as to be cooperable with the support structure.

2. The handle arrangement of claim 1, wherein the latching mechanism has a latched first state corresponding to a position of the handle when in the stowed state of the handle.

3. The handle arrangement of claim 1, wherein the latching mechanism has an unlatched second state corresponding to a position of the handle when in the deployed state.

4. The handle arrangement of claim 1, wherein the latching mechanism is unlatched by an initial movement of the handle in a direction away from the position of a handle when in the deployed state, whereafter the latching mechanism automatically then pushes the handle towards the deployed state.

5. A body component for a vehicle comprising a door panel having an outer surface that defines an aperture for receiving the handle of the retractable handle arrangement of claim 1, wherein the handle is received within the aperture.

6. The body component according to claim 5, wherein the handle has an outer surface which is shaped to correspond to the aperture.

7. The body component according to claim 5, wherein the outer surface of the handle lies flush with the outer surface of the panel when the handle is in the stowed state.

8. The body component according to claim 5, wherein the latching mechanism of the handle arrangement is unlatched by an initial movement of the handle in a direction away from a position of the handle when in the deployed state, whereafter the latching mechanism automatically then pushes the handle towards the deployed state and wherein said initial movement of the handle comprises moving the door handle to a position in which the handle is recessed below the outer surface of the door panel adjacent the handle.

9. A vehicle including the body component of claim 5.

10. A vehicle including the retractable handle arrangement of claim 1.

11. A retractable handle arrangement comprising a handle that is movable between a stowed state and a deployed state by an electrical drive mechanism, wherein the handle comprises a handle loop and the handle is also movable into the deployed state from the stowed state by an emergency deployment mechanism that is separate from the electrical drive mechanism, wherein the emergency deployment mechanism is a manually actuated two-state latching mechanism operable between a compressed state and an extended state;

wherein in transitioning from the compressed state to the extended state, the latching mechanism is arranged to bear against a support structure and exert a force on the handle to urge the handle into the deployed state, and wherein the latching mechanism is located on an inboard side of an inner member of the handle loop and extends away from the inner member so as to be cooperable with the support structure.
