A stroller seat has a seat back, a seat bottom, a seat hub assembly joining the seat back to the seat bottom, and an actuator carried on the seat. The actuator can be actuated to permit adjusting the recline angle of the seat back and seat bottom as a unit and can be actuated to permit folding the seat back relative to the seat bottom.

Foldable, removable, reversible stroller seat

A roller system including a frame, a plurality of arm assemblies configured to apply a force to a surface, each arm assembly including an arm pivotably connected to the frame and a roller assembly pivotably connected to the arm and having a plurality of rollers configured to engage with the surface, and a pressure distribution system configured to adjust the force applied to the surface by at least one of the plurality of arm assemblies.

Roller system

A foldable stroller has a frame assembly with a frame fold joint and is reconfigurable between an in-use configuration and a folded configuration. A child support structure is repositionable between a usable state on the frame assembly in the in-use configuration and an unusable state not suitable to support a child on the frame assembly. An interlock mechanism cooperates with the child support structure and is movable between a locked state preventing the frame assembly from being folded from the in-use configuration to the folded configuration and an unlocked state permitting the frame assembly to be folded. With the frame assembly in the in-use configuration and the child support structure on the frame assembly in the usable state, the interlock mechanism is retained in the locked state. The interlock mechanism is unlocked when the child support structure is moved to the unusable state.

Foldable stroller and fold interlock mechanism

In an implementation, a roller system is provided. The roller system includes a modular frame. The frame includes a plurality of weight component attachment points. Each weight component attachment point is adapted to receive one or more weight components such that a weight of the frame and location of a center of gravity of the frame is adjusted by the addition of one or more weight components to each of the plurality of weight component attachment points. The frame further includes at least one arm assembly adapted to connect to the frame, and to apply force to a surface, wherein the force applied to the surface is proportional to the weight of the frame and the location of the center of gravity of the frame.

Modular roller system

A stroller has a frame assembly, a seat assembly mounted to the frame assembly, and a hub assembly carried by the seat assembly. The hub assembly has a hub axis, a first hub part connected to the stroller, and a second hub part connected to the first hub part and to the seat assembly. A cup holder is connected to the first hub part. The second hub part and the seat assembly can be rotated about the hub axis relative to the first hub part to adjust a recline position of the seat assembly while the cup holder does not rotate therewith.

Stroller and seat assembly

A stroller includes a frame, a pivot joint assembly mounted on the frame, and a handle coupled to the frame at the pivot joint assembly. The handle rotates about a pivot axis defined by the pivot joint assembly between first and second positions relative to the frame. A latch assembly includes a projection and is movable between a latched state in which the latch assembly secures the handle in either the first position or the second position and a released state in which the handle is released for movement between the first and second positions. A latch guide defines a path along which the projection rides during the movement between the first and second positions such that the projection remains in the released state during the movement between the first and second positions

Reversible stroller handle

A stroller includes a frame assembly, a seat supported by the frame assembly, and first and second adjustable seat supports engaged with the frame assembly to support the seat in a position relative to the frame assembly. A link couples the first and second seat supports such that a movement of the first seat support is mirrored in a corresponding movement of the second seat support to adjust the position of the seat.
