Abstract
A personal mobility vehicle, such as a stroller, has spaced apart side frame assemblies that each include a backrest portion and a seat frame portion. The backrest portion is moveable to several recline positions relative to the seat frame portion by actuating a latching mechanism. The backrest portion and the base frame are both moveable to a folded position relative to the seat frame by actuating the same latching mechanism. The side frame assembly further has a tilt mechanism that permits the backrest and seat frames to move as a unit relative to the base frame.
Claims14
A side frame assembly of a personal mobility vehicle comprising:
- a base frame assembly;
- a seat frame having a rail housing that supports a folding actuation rail and a recline adjustment rail for relative linear movement and concurrent linear movement, the folding actuation rail configured to be selectively fixed relative to the rail housing between a first position of the base frame assembly and a second position of the base frame assembly that is more compact than the first position;
- a backrest cane pivotally attached to the seat frame;
- a backrest link pivotally attached to the backrest cane and pivotally attached to the recline adjustment rail such that pivoting movement of the backrest cane moves the folding actuation rail between the first and second positions.
