A wheelchair includes a seating portion on which a wheelchair user sits, a body frame that supports the seating portion, a pair of rear wheels and a pair of front wheels rotatably supported by the body frame, and a seat back portion capable of changing the inclination angle with respect to the seating portion. The wheelchair includes push-along handle portions as engaging portions capable of fixing the seat back portion to a side sill as a vehicle body member that forms a door opening of the vehicle when the seat back portion is tilted backward of the wheelchair.

A seat is disclosed herein having a backrest, a base for receiving a posterior of a human user, and an incline adjuster having a shaft, a lever, a follower, and a rack the shaft being moveable to swing the lever to cause a follower into or out of locking engagement with the rack, an arrangement being such that when the follower is in an unlocked disposition the rack can move to adjust an incline of the backrest and the base.

Provided is a robot. The robot includes a main body provided with a traveling wheel, a seat disposed above the main body, a backrest spaced apart from the seat, a link configured to connect the seat to the backrest, a first tilting mechanism embedded in the seat, the first tilting mechanism being configured to tilt the link with respect to the seat, and a second tilting mechanism embedded in the backrest, the second tilting mechanism being configured to tilt the backrest with respect to the link.

A modular seat apparatus includes a base cushion and a back cushion that includes a plurality of segments defining a longitudinal length of the back cushion. The back cushion is pivotably coupled to the base cushion such that the back cushion is oriented at an angle relative to the base cushion. The plurality of segments is configured to translate in response to the back cushion pivoting relative to the base cushion such that the longitudinal length of the back cushion decreases as the angle increases and the longitudinal length of the back cushion increases as the angle decreases.

A user control device for a transporter. The user control device can communicate with the transporter via electrical interface(s) that can facilitate communication and data processing among the user interface device and controllers that can control the movement of the transporter. The user control device can perform automated actions based on the environment in which the transporter operates and the user's desired movement of the transporter. External applications can enable monitoring and control of the transporter.

Inter-alia, a method is disclosed comprising: obtaining one or more first fallback objects indicative of a geographic area that is covered by one or more cells of a communication network; obtaining one or more pieces of cell information indicative of a number of positioning requests that a respective cell of the one or more cells has received; determining one or more second fallback objects out of the one or more fallback objects; determining for an area of the respective second fallback object in that the needed level of accuracy for determining a position is not achievable, one or more cells based at least partially on the one or more pieces of cell information; and outputting the determined one or more second fallback objects and/or the determined one or more cells for usage in a generation of a radio map. It is further disclosed an according apparatus, computer program and system.

Embodiments of the present invention provide a dental treatment machine for children. The dental treatment machine may include a base, a cushion and a backrest, where the vertical distance between the base and the cushion, the angle between respective planes of the cushion and the backrest, as well as the horizontal distance between the cushion and the backrest are selectively adjustable according to a child's figure. Preferably, the vertical distance adjustment between the cushion and the base is about 350-730 mm, the angle adjustment between the backrest and the cushion is about 0°˜68°, and the distance adjustment between the backrest and the cushion is about 0˜50 mm.

A multifunctional wheelchair contains: a body, a support plate, a lifting seat, and a shampoo basin. The body includes a retractable mounting, a chair back, at least one drive device, and two frames. The two frames have two main wheels, the two frames have two guide wheels, and the two armrests are arranged on a second drive device. A respective armrest has an abutting portion, and the retractable mounting have two racks. The support plate is detachably engaged on the retractable mounting of the body. The lifting seat is removably engaged on the retractable mounting of the body, and the lifting seat includes a saddle on a third drive device which is configured to drive the saddle to lift or descend adjustably. The shampoo basin is detachably connected on the chair back and included a washing chamber.

Modular chair systems and methods of transporting a subject using a modular chair system are described. A modular chair system includes a seat component, a chair component, and a wheelchair component. The seat component includes a seat having a planar lower surface with one or more recesses and one or more attachment bars disposed in each of the recesses. The chair component includes one or more chair latch mechanisms and the wheelchair component includes one or more wheelchair latch mechanisms. Each attachment bar corresponds to one of the chair latch mechanisms and one of the wheelchair latch mechanisms such that the seat component is configured to be placed upon the chair component or the wheelchair component and releasably held in place by the chair latch mechanisms or the wheelchair latch mechanisms.

A resilient backrest dampening mechanism is provided for use with chairs having a seat and a backrest, the mechanism comprising four pivot points; a first pivot point arranged on a base different from the backrest; a second pivot point arranged at a distance from the first pivot point on the base, wherein a bracket is pivotally connected to the second pivot point; a third pivot point provided between the bracket and a first end of a backrest connection member, and the backrest connection member being adjustably connected to the backrest; a fourth pivot point provided in the bracket; a resilient member arranged between the fourth pivot point and the first pivot point, and wherein all the pivot points pivot around corresponding axes and all of the axes are parallel.
