1. A stroller, comprising:
- a first stroller component;
a second stroller component;
at least one of the first and second stroller components being movable from a first position to a second position;
a drive mechanism operatively engaged with the at least one of the first and second stroller components to move the at least one of the first and second stroller components from its first position to its second position;
a user-controlled disengaging mechanism for disengaging the operative engagement between the drive mechanism and the at least one of the first and second stroller components to allow a user to manually move at least one of the first and second stroller components from the first position to the second position when at least one of a) power supplied to the drive mechanism is not sufficient to actuate the drive mechanism to move at least one of the first and second stroller components from its first position to its second position and b) a failure with at least one of the first stroller component, the second stroller component, and the drive mechanism has occurred;
one or more latches in operative engagement with at least one of the first stroller component and the second stroller component, which one or more latches are moveable by one or more latch drive mechanisms operatively connected thereto between a latched position in which the one or more latches prevent movement of at least one of the first stroller component and the second stroller component toward their second positions, and an unlatched position in which the one or more latches allow movement of at least one of the first stroller component and the second stroller component toward their second positions; and
a manual latch release mechanism operatively connected to the one or more latches to allow manual movement of the one or more latches from the latched position to the unlatched position when at least one of failure of the latch drive mechanism and obstruction of the latch drive mechanism has occurred.

Abstract
A stroller includes: a first stroller component; a second stroller component comprising a child receiving portion; a drive mechanism operatively engaged with at least one of the first and second stroller components to move the at least one of the first and second stroller components from a first position to a second position; and an object sensor operably coupled to the child receiving portion. The object sensor provides a signal that prevents movement of the first and second stroller components from the first position to the second position if the object sensor detects the presence of an object in the child receiving portion.

9. A stroller, comprising:
-
a collapsible carriage frame movable between a collapsed position and an open position; a drive mechanism operatively engaged with the collapsible carriage frame to move the collapsible carriage frame from the collapsed position to the open position; and a user-controlled disengaging mechanism for disengaging the operative engagement between the drive mechanism and the collapsible carriage frame to allow a user to manually move the collapsible carriage frame from the open position to the collapsed position when at least one of a) power supplied to the drive mechanism is not sufficient to actuate the drive mechanism to move the collapsible carriage frame from the open position to the collapsed position and b) a failure with at least one of the collapsible carriage frame and the drive mechanism has occurred; one or more latches in operative engagement with the support structure, the one or more latches moveable between a latched position and an unlatched position by at least one latch drive mechanism; and a manual latch release mechanism operatively connected to the one or more latches to allow manual movement of the one or more latches from the latched position to the unlatched position when at least one of failure of the latch drive mechanism and obstruction of the latch drive mechanism has occurred. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
