Abstract:
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; and a 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.
