  • Retractable step system for getting into and out of a vehicle, and vehicle door assembly provided with such a system
    Patent number: 11312307
    Abstract: A retractable step system for getting into and out of a vehicle has at least one step and a supporting element, which carries the step and is movable between a raised position and a lowered position; in the lowered position, the step projects from the supporting element along a first horizontal axis so as to allow a user to place a foot on it; the system has a control member, which can be manually operated, and a stop device, which holds the supporting element in the raised position, when the control member is arranged in a first position, and allows the supporting element to freely move to the lowered position, when the control member is arranged in a second position; the control member has a retention portion, which, in the second position, projects along a second horizontal axis, which is orthogonal to the first horizontal axis, so as to keep, in use, a vehicle door open.
