Methods and devices for adjusting the position of a seat in a vehicle are described herein. The methods include obtaining pressure values output by a plurality of sub-sensors; calculating a mean square value and an average value of the pressure values output by the sub-sensors; judging whether a ratio of the mean square value to the average value is greater than a preset value; obtaining pressure values output by a front pressure sensor, a rear pressure sensor, a left pressure sensor and a right pressure sensor when the ratio of the mean square value to the average value is greater than the preset value; adjusting fore-and-aft positions of the seat according to the pressure values output by the front pressure sensor and the rear pressure sensor; and adjusting lateral positions of the seat according to the pressure values output by the left pressure sensor and the right pressure sensor.

An user interaction system for performing interaction with a user based on recognition of a sitting posture of the user includes a posture recognition seat including a posture recognition sensor for recognition the sitting posture of the user, and at least one communication module for communication with an external device, a posture mimicking animated device including a communication module for performing communication with the communication module of the posture recognition seat, wherein the posture mimicking animated device visually mimics the sitting posture of the user or visually or audibly guide the sitting posture of the user, in accordance with state information about the sitting posture of the user determined based on a sensing result obtained by the posture recognition sensor, and a mobile application installed in a communication device possessed by the user, wherein the mobile application receives synchronized information related to the sitting posture of the user via communication with the posture recognition seat, and generates user interaction information corresponding to the received information and displays the user interaction information on an application screen.

A chair is provided including a subframe, a seat element, a back element, a spring mechanism and an adjustment device. The spring mechanism includes a leaf spring, which is clamped on one side in the subframe, and a support, which is movable on a track between the leaf spring and the subframe. The adjustment device includes an adjustment member and a transmission mechanism. A movement of the adjustment member is translated into a movement of the support at a transmission ratio in a range of 1:0.5 and 1:4.

A vehicle seat that includes: a seat cushion that is configured to be raised and lowered in a seat vertical direction; a buckle that is attachable to an attachment location that is not subject to the raising or lowering of the seat cushion, and that retains a tongue provided at an elongated belt shaped webbing, in a state in which in the webbing is worn over at least a pelvis area of the occupant; and a lifting device that is actuated, in a case in which a collision of a vehicle has been detected, so as to move the occupant, in a case in which the occupant is sitting on the seat cushion, toward an upper side of the seat at a location further toward a rear side of the seat than a central portion of the seat cushion in a front-rear direction of the seat.

Disclosed is a system for correcting a passenger's posture in an autonomous vehicle, wherein the system includes a camera configured to measure a distance between a headrest and a head of the passenger, a plurality of body pressure sensors configured to be uniformly embedded across an entire area of the seat and sense body pressures of the passenger, a pressurizing device configured to be expandably installed inside a seatback and press between T10 and T12 of a thoracic spine of the passenger, and a controller configured to control an operation of the pressurizing device on the basis of the distance measured by the camera and a scapular pressure of the passenger, which is sensed by the plurality of body pressure sensors.

A support surface including a cutout on a bottom surface of the support surface. The cutout, which can include a plurality of cutouts, provides a controlled structural collapse of the support surface by varying a stiffness in a cross-section. That is, the area in which the cutouts are positioned collapses more easily than the surrounding area of the support structure, thus making the area with the cutouts perceived as being softer. The cutouts can reduce the peak pressures on the portion of the user's body (for example, the user's ischial tuberosities) that is positioned over the cutouts. The support surface can also include a low-friction interface extending across a top surface of the support surface.

Disclosed herein is a reconfigurable apparatus that includes a backrest, a seat coupled with a column, a linkage statically attached to the backrest, a leaf spring in direct contact with the linkage, a first structure fixed to the column, and a second structure. The first and second structures each have one or more teeth. The chair is also configured such that when a weight is applied to the seat, the one or more teeth of the second structure move along the one or more teeth of the first structure to thereby shorten a working length of the leaf spring and provide an increased resistance to tilting of the backrest relative to the column. A process for assembling the reconfigurable apparatus is also described herein.

A method for fabricating custom seat bolsters includes receiving a first image of a user in a first pose and a second image of the user in a second pose. The method further includes generating a 3D body scan model based on at least the first image of the user and the second image of the user. The method further includes determining a design for a set of seat bolsters for the user based on the 3D body scan model. The method further includes providing the set of seat bolsters for the user based on the determined design.

A system of controlling various actuators associated with human support surfaces is disclosed. Such a system is made up of a support surface, a controller, and an actuator. The system may optionally include batteries, a means of charging the batteries, and a graphical user interface as well as a communication link between the graphical user interface and the support surfaces. The actuators are capable of altering contour and/or firmness, of a support surface, they may be vibrational or heating/cooling in nature, and they may also alter the overall relative position of a support surface to another support surface, and/or to the ground plane.

Surgical robotic systems including a user console for controlling a robotic arm or a surgical robotic tool are described. The user console includes components designed to automatically adapt to anthropometric characteristics of a user. A processor of the surgical robotic system is configured to receive anthropometric inputs corresponding to the anthropometric characteristics and to generate an initial console configuration of the user console based on the inputs using a machine learning model. Actuators automatically adjust a seat, a display, or one or more pedals of the user console to the initial console configuration. The initial console configuration establishes a comfortable relative position between the user and the console components. Other embodiments are described and claimed.
