A pushchair seat (10) comprising a seat back (18) mounted for pivotable movement relative to a seat base (20). A bumper bar (14) is pivotably coupled to and carried by the seat (10) and is moveable between a stowed position generally adjacent to the seat base (20) and a deployed position spaced from the seat back (18) and the seat base (20). Drive mechanisms (16) are provided at each end of the bumper bar (14) and comprise a selectively engageable coupling mechanism in the form of a clutch mechanism (30, 32) and a control mechanism (34, 56, 58). The coupling mechanism couples movement of the seat back (18) between its stowed position and its operating position into a corresponding movement of the bumper bar (14) between its stowed position and its deployed position.

1. A seat for a pushchair, the seat comprising: a seat body comprising a seat back and a seat base, the seat back being mounted for pivotable movement relative to the seat base and being movable between a stowed position generally adjacent to the seat base and an operating position spaced from and extending generally upwardly from the seat base;a bumper bar pivotably coupled to and carried by the seat body, the bumper bar being movable between a stowed position generally adjacent to the seat base and a deployed position spaced from the seat back and the seat base; anda drive mechanism comprising a selectively engageable coupling mechanism provided between the seat back and the bumper bar and operable to couple movement of the seat back between its stowed position and its operating position into corresponding movement of the bumper bar between its stowed position and its deployed position, and a control mechanism operable to disengage the selectively engageable coupling mechanism once the bumper bar has reached its deployed position, such that the relative positions of the bumper bar and the seat base become fixed;wherein the selectively engageable coupling mechanism comprises a clutch mechanism comprising a driving member coupled to the seat back and a driven member coupled to the bumper bar, the driving member being arranged such that as the seat back is moved the driving member engages with the driven member and causes the driven member to rotate, thereby causing corresponding movement of the bumper bar, and the driving member is provided with a cam member and the driven member is provided with a cam follower. 2. A seat as claimed in claim 1, wherein: the control mechanism is further operable to engage the selectively engageable coupling mechanism as the seat back is moved from the operating position towards its stowed position. 3. A seat as claimed in claim 1, wherein: the driven member is carried by the bumper bar and is rotationally fixed relative to the bumper bar and mounted for axial movement relative to the bumper bar. 4. A seat as claimed in claim 1, wherein: the driving member is arranged such that as the seat back is unfolded from its stowed position to an intermediate position the driving member is brought into engagement with the driven member, and as the seat back is subsequently moved from the intermediate position towards the operating position the driving member causes the driven member to rotate, thereby moving the bumper bar from its stowed position towards its deployed position. 5. A seat as claimed in claim 1, wherein: the cam member and the cam follower are arranged such that a first rotational movement of the driving member causes the cam member to engage with the first cam follower and subsequent rotational movement of the driving member causes the driven member to correspondingly rotate. 6. A seat as claimed in claim 1, wherein: the cam member and the cam follower are arranged such that movement of the cam member starts from a position of engagement with the cam follower and rotational movement of the drive member causes the driven member to correspondingly rotate. 7. A seat as claimed in claim 1, wherein: the driving member is arranged such that as the seat back is moved from its operating position to an engagement position in the region of the deployed position of the bumper bar the driving member is brought into engagement with the driven member, and as the seat back is subsequently moved towards its stowed position the driving member causes counter-rotation of the driven member, thereby moving the bumper bar towards its stowed position. 8. A seat as claimed in claim 1, wherein: the control mechanism comprises an actuator operable to move the driving member axially relative to the driven member, such that the cam member is moved out of alignment with the cam follower. 9. A seat as claimed in claim 8, wherein: the driven member comprises a recess adapted to at least partially receive the driving member when it is out of alignment and in which the driven member is free to rotate. 10. A seat as claimed in claim 8, wherein: the control mechanism further comprises a locking socket provided on the seat base and a key member provided on the driven member, the locking socket being adapted to at least partially receive the driven member and the key member, and the actuator is adapted to bias the driven member towards the locking socket such that when the bumper bar reaches its deployed position, the key member becomes aligned with the locking socket and the actuator causes axial movement of the driven member and the key member into the locking socket. 11. A seat as claimed in claim 8, wherein: the cam member and the cam follower are arranged such that a first counter-rotational movement of the driving member causes the cam member to engage with the cam follower and subsequent counter-rotational movement of the driving member releases the driven member from the locking socket and causes the driven member to correspondingly rotate, causing the bumper bar to move towards its stowed position. 12. A seat as claimed in claim 11, wherein: the cam member has a ramped leading edge, such that the subsequent counter-rotation of the driving member causes axial movement of the driven member out of the locking socket. 13. A seat as claimed in claim 1, wherein: the seat further comprises a mechanical ratchet mechanism coupled between the seat back and the seat base and operable to control movement of the seat back between its operating position and a reclined position. 14. A seat as claimed in claim 1, further comprising: attachments means for attaching the seat to a pushchair frame including a push/pull handle, a front wheel frame on which at least one front wheel is rotatably mounted, and a rear wheel frame on which at least one rear wheel is rotatably mounted. 15. A pushchair comprising: pushchair frame including a push/pull handle, a front wheel frame on which at least one front wheel is rotatably mounted, and a rear wheel frame on which at least one rear wheel is rotatably mounted; anda seat as claimed in claim 1, wherein the seat further comprises attachments means for attaching the seat to the pushchair frame.
