A dynamic ergonomic surface system for use in a motor vehicle includes an ergonomic surface that is inlayed in a surrounding surface and transitions between states, including: a neutral state in which the ergonomic surface is consistent with the surrounding surface, and at least one ergonomic support state in which the ergonomic surface provides ergonomic support for a user operating an input device. The dynamic ergonomic surface system also includes a sensor system that detects events triggering the transition between states, and a controller that controls the ergonomic surface to transition between the states in response to the detected events.

A body-size class specification device of the present invention comprises a class feature-quantity information memorizing section to memorize class feature-quantity information to correlate plural classes for classifying a body size according to a dimension ratio of prescribed parts of a body with plural prescribed feature quantities for characterizing the plural classes, a first input section as an example of a feature-quantity acquiring section to acquire feature quantity of an object person to be specified for the class, an eye-height measuring section and an upper-body-length-ratio processing section, and a class specifying section to specify the class corresponding to the feature quantity of the object person acquired by the feature-quantity acquiring section based on the class feature-quantity information memorized by the class feature-quantity information memorizing section.

The present disclosure provides a vehicle seat having a legrest with a seat cushion function, which may mount a legrest on a back portion of a front seatback to be deployable such that a passenger seated on a rear seat may place and support a calf and a foot on the deployed legrest, and recline a front seatback forward to use the deployed legrest as a seat cushion on which the passenger may be seated while facing a passenger seated on the rear seat.

The present disclosure is directed to an automatic seat height system that adjusts a seat height. The height of a seat is adjusted only when a calculated seat height is outside of the range of a desired seat height. The seat is adjusted only when a seat height change from the desired seat height is not due to external forces such as vibration or shock. The seat height apparatus comprises a sensor, a height adjustment apparatus, a controller and a controllable actuator all in operable communication. The controller comprises software that calculates a calculated seat height based on a measured raw seat height. The calculated seat height is a time history position value pattern. The controller then compares the calculated seat height to a desired seat height to determine a change factor. If the change factor is outside of a predetermined range, the controller directs the controllable actuator to change the height of the seat to bring it within the range.

Body measurements of a person may be scanned using a camera (e.g., a camera on a mobile phone. Vehicle settings may then be determined based on the body measurements. Example vehicle settings may include one or more of a position of a heads-up display, a position of a pedal, an angle of a backrest, a height of a seat cushion, a tilt of the seat cushion, an extension position of the seat cushion, a position of a lumbar support, a position of a seat side bolster, a position of a headrest, a position of a side mirror, a position of a rear-view mirror, a tilt of a steering wheel, and/or a position of a steering wheel.

A multi-position seat configured to maximize usability thereof through various changes in the positions of a seat back and a seat cushion may include a height assembly configured to move a base frame mounted on a vehicle body, a slide assembly configured to move a seat cushion frame, which is positioned above the base frame and is connected to the base frame via a link mechanism, upwards and downwards by sliding action of the link mechanism in a forward and backward direction, a tilt assembly configured to move a rear end portion of the seat cushion frame upwards and downwards, and a seat back frame hingedly coupled to a rear end portion of the base frame to be reclined.

[Object] To inhibit leg rests from colliding with each other and to allow a leg rest of his/her own seat to operate even in the case where a power source failure or the like occurs. [Solving Means] A seat apparatus according to an embodiment of the present invention includes: a seat body; a control unit; and a setting means. The seat body includes a leg rest. The control unit includes a controller. The controller determines whether the seat body is in a first state in which the seat body does not face a front seat or a back seat of the seat body or a second state in which the seat body faces one of the front seat and the back seat. The controller enables, where the controller has determined that the seat body is in the first state, a tilt operation command for the leg rest to tilt forward, and invalidates, where the controller has determined that the seat body is in the second state, the tilt operation command. The setting means fixes the determination result by the controller to the first state.

A floating seat may have at least one seat shell with a seat surface region and a backrest region. The seat may also have a base element on which the seat shell is arranged in an adjustable manner, and an adjustment mechanism for adjusting the seat shell relative to the base element and/or a seat base. The adjustment mechanism has at least one adjustment unit for adjusting the seat shell and at least one drive unit which is designed to lock the base element and the seat shell in place in a self-locking manner. The lock can be released by a force introduced into the adjustment unit by an occupant sitting in the seat shell via said seat shell as well as by a force introduced into the adjustment unit by the drive unit.

A system for optimizing the positioning of a vehicle seat includes: a module for obtaining and saving at least one morphological parameter of a passenger on the seat; a seat positioning adjustment module having at least one sensor within the vehicle, controlling the positioning; and a module for determining the positioning adjustment to be applied as a function of the morphological parameter. The system is configured to: determine at least one adjustment change that optimises passenger comfort to be applied during vehicle operation, automatically alter the position of the seat to achieve the adjustment change, or signal the passenger of the adjustment change to be applied, via an interaction module, and guide the passenger to manually achieve the adjustment change, via a predetermined sound or light signal.
