Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
Pushchair comprising a frame onto which is hinged a reclinable backrest (24), the frame supporting arms (20) on opposing sides of the reclinable backrest (24) which are pivotally rotatable in a vertical plane between a first position and a second position, each arm (20) comprising a plurality of engaging notches (19) disposed along a path (23) along which slide pins (18) protruding laterally from the backrest (24), in the first position each arm (20) engaging with one of the notches (19) the corresponding pin (18) protruding from the backrest, so as to block the movement of the backrest in a pre-established angular position, and in the second position disengaging the notches (19) of the plurality from the pin (18) to allow free movement of the backrest, characterized by the fact that disposed on the backrest are means which have a manual control element (49) to engage the arms (20) and move them simultaneously between the first and the second position.
Claim 2
Dependent Claim
46 words
Pushchair as claimed in claim 1, characterized by the fact that the first position of the arm (20) is a lowered position and the second position is a raised position, the movement between the first and second position occurring against the action of a spring (22).
Claim 3
Dependent Claim
78 words
Pushchair as claimed in claim 1, characterized by the fact that the engaging means comprise a movable element (37) disposed on the backrest close to each arm (20), each movable element having a kinematic link with the control element (49) to shift, upon operation of the control element, between a first position of non-interference and a second position of interference with the corresponding arm in which said movable element (37) biases the arm (20) towards the second position.
Claim 4
Dependent Claim
53 words
Pushchair as claimed in claim 3, characterized by the fact that each movable element is composed of a tooth (37) protruding from an element (39) pivoted to the backrest so as to rotate on command of the control element (49), the positions of interference and non-interference being angular positions of the pivoted element.
Claim 5
Dependent Claim
30 words
Pushchair as claimed in claim 3, characterized by the fact that the kinematic link comprises a tie (41) connected between the rotatably pivoted element (39) and the control element (49).
Claim 6
Dependent Claim
18 words
Pushchair as claimed in claim 5, characterized by the fact that the tie (41) is a flexible cable.
Claim 7
Dependent Claim
35 words
Pushchair as claimed in claim 5, characterized by the fact that the control element (49) is a handle pivoted to the backrest so as to move between a rest position and a tie pulling position.
Claim 8
Dependent Claim
39 words
Pushchair as claimed in claim 3, characterized by the fact that the movement of the movable element (37, 39) between the first position of non-interference and the second position of interference occurs against the action of a spring (40).
Claim 9
Dependent Claim
25 words
Pushchair as claimed in claim 1, characterized by the fact that the frame and the backrest can be folded at least in a crosswise direction.
Claim 10
Dependent Claim
54 words
Pushchair as claimed in claim 9, characterized by the fact that the backrest comprises a central body (33) supporting the control element (49) and connected to lateral uprights (12) of the backrest by means of pairs of arms (27, 28) hinged so as to form a double parallelogram for crosswise folding of the backrest.
Claim 11
Dependent Claim
38 words
Pushchair as claimed in claims 3 and 9, characterized by the fact that the movable elements (37, 39) are each disposed close to the pivots between one of the arms of the pair and the relevant upright (12).
Claim 12
Dependent Claim
34 words
Pushchair as claimed in claims 6 and 11, characterized by the fact that the cable (41) runs through a housing (45, 43) made in the body and through said one arm of the pair.
