Abstract: A wearable sitting-posture assisting device includes at least one leg unit that defines at least one longitudinal leg axis, and includes at least one foot unit that is configured for a connection of a shoe and/or a foot of a person, wherein the foot unit includes at least one shoe adapter and at least one shoe connector, which are couplable with one another at least transversely to the at least one at least one longitudinal leg axis, wherein the wearable sitting-posture assisting device includes a quick coupling which is configured for a tool-less coupling of the shoe adapter and the shoe connector with each other, wherein the quick coupling includes at least one latch element that is configured at least partially to create a coupling of the shoe adapter with the shoe connector.

Abstract: A wearable sitting-posture assisting device includes at least one leg unit that defines at least one longitudinal leg axis, and includes at least one foot unit that is configured for a connection of a shoe and/or a foot of a person, and includes at least one bearing unit supporting at least a portion of the foot unit such that it is translationally movable at least transversely to the at least one longitudinal leg axis. The bearing unit comprises at least one reset element, which is configured, in at least one bearing position, to apply a reset force to at least a portion of the foot unit.

Abstract: A wearable sitting posture assisting device includes at least one leg unit featuring at least one knee joint and featuring at least one locking unit for the knee joint; includes at least one second leg unit featuring at least one second knee joint and featuring at least one second locking unit; and includes at least one actuation unit featuring at least one manually operable actuation element for mechanically controlling the locking unit and/or the second locking unit.

Abstract: A leg unit for a wearable sitting posture assisting device, comprises an upper support designed to receive a weight force of a person, a lower support designed to transmit the person's weight force to a ground, a joint connecting the at least two supports to each other, and a blocking means implementing a blocked state to block the joint at at least one sitting angle corresponding to an at least partly sitting posture, the leg unit comprising a guiding means for the blocking means, which guiding means is designed to allow a rotation of the joint while the blocking means is in the blocked state, to a wearable sitting posture assisting device, comprising two of these leg units, and to a method to block such a wearable sitting posture assisting device in an at least partly sitting posture.

Abstract: A seat unit for a wearable sitting posture assisting device includes at least one sitting means designed to form an adjustable and/or self-adjusting seat surface to be used in at least one at least partly sitting posture and in a walking mode, and a frame means designed to receive a weight force of a person sitting on the sitting means that is mounted on the frame means, and to a wearable sitting posture assisting device with such a seat unit.
