A vehicle is disclosed with a seating assembly which is capable of prompting an occupant to take an appropriate riding posture depending on the behavior of the vehicle body. A motorcycle includes tilting mechanisms for tilting seating surfaces of a front seat (rider seating part) and a rear seat (passenger seating part) and an ECU carries out a control process for tilting the seating surfaces to lift rear portions of the seats upwardly in response to an action to accelerate the motorcycle and a control process for tilting the seating surfaces to lift front portions of the seats upwardly in response to an action to decelerate the motorcycle.

A vehicle seat includes a seat bottom adapted to slide along a floor, a seat back coupled to the seat bottom, and powered means for rearranging the vehicle seat by sliding the seat bottom along the floor and/or pivoting the seat back relative to the seat bottom.

A system and a control method can prevent interference between front and rear seats for a vehicle, and allow reclining control and slide control for the front and rear seats to be performed, to control a seat back rearward movement angle of a front seat based on a seat back angle of the front seat, a position of the rear seat, and an interval between the front and rear seats at the time of rearward reclining control for the front seat, control a rearward slide movement distance based on the seat back angle of the front seat at the time of rearward slide control for the front seat, and calculate in advance a likelihood that interference will occur between the front and rear seats so as to stop the control operation at the time of performing a rearward reclining control operation and a rearward slide control operation.

A vehicle seat including a seat that includes a seat cushion and a seat back; an inclination drive portion configured to incline the seat back; and a slide mechanism configured to enable the seat to slide in a vehicle front-rear direction, in which the slide mechanism includes: a slide rail that includes an upper rail and a lower rail and supporting the seat to be able to move in a sliding manner in the front-rear direction, a slide drive portion configured to enable the upper rail to slide with respect to the lower rail, and a mode switching switch configured to enable switching between modes, in a normal mode, a slide range of the seat in the front-rear direction is a slide amount used when the vehicle is driven, in a relaxing mode, a slide amount is at a position where a slide position of the seat in the front-rear direction is rearward, with respect to a slide position at a rearmost end in the normal mode, and the mode switching switch is disposed on a front side where a switch operation is not able to be performed from the slide position of the seat corresponding to a slide amount in the relaxing mode.

The present invention includes a vehicle seat having a seat portion and a seatback. The vehicle seat further includes a plurality of air bladders disposed in the seat portion and a plurality of air bladders disposed in the seatback. The air bladders are configurable between fully inflated condition, fully deflated condition, and plurality of semi-inflated conditions. A controller is configured to control air bladder inflation, wherein the air bladders deflate to the fully deflated condition in response to an access signal received by the controller. The controller is further configured to control the seat position with regards to vertical and horizontal positions to provide greater access to the vehicle interior when entering or exiting the vehicle.

A vehicle seat includes: a seating portion configured to support a seated occupant in a seating posture; a shell portion configured to cover the circumference of the seating portion including side portions of the seated occupant from a rear side of the occupant; a first moving device that is configured to move a relative position of the seating portion with respect to a vehicle; and a second moving device that is configured to move a relative position of the shell portion with respect to the seating portion, the second moving device being configured to move at least side portions of the shell portion to a first position at which the side portions of the seated occupant is covered by the shell portion and to a second position at which the side portions of the seated occupant is uncovered by the shell portion.

A vehicle seat includes a seat foundation coupled to a floor of a vehicle, a seat bottom coupled to the seat foundation to move back and forth along a longitudinal axis relative to the floor, and a seat back coupled to the seat bottom to extend upwardly away from the seat bottom. The seat back pivots about an axis relative to the seat bottom.

A seat drive device is provided with: a single rotary motor; a plurality of operating members, which are arranged to correspond to a plurality of positioning mechanisms; a plurality of tubular members, which are arranged to correspond to the positioning mechanisms and selectively connect an output shaft to the positioning mechanism corresponding to the operating member operated with the operation of any one of the operating members and input shafts rotated by the rotary motor; and a single switch, which passes an electric current through the rotary motor with a polarity corresponding to the direction of the operation with the operation of any one of the operating members.

A method for operating a vehicle seat device for motor vehicles, which has a vehicle seat with a seat part and a backrest, associated with the seat part, and at least one actuator which is associated with the seat part and/or the backrest and by means of which the vehicle seat can be brought automatically into a sitting position and into a reclining position, wherein the movement takes place as a function of a desired position that can be specified by a user and of at least one detectable vehicle seat state. It is provided that a current temperature is monitored as the vehicle seat state and that if the monitored temperature falls below a limit temperature, the vehicle seat is brought into a sitting position or left in a current sitting position regardless of the desired position.

The present disclosure relates to methods and system for acquiring and analyzing biosignals or physiological signals of a person sitting in a vehicle and predicting (in real-time) time-varying attention, engagement level or alertness level using the biosignals. The biosignals may be acquired using one or more clusters of electrodes together with a wearable user device or from a sensing device that is embedded in the seat of the vehicle. In some embodiments, the biosignals may be utilized to predict restedness level of the subject, to monitor or predict physiological state of the subject, to detect a distress situation and to adapt a vehicle control accordingly. In some other embodiments, the biosignals can be transformed into communication, for example, speech signals or instructions for the vehicle. One or more actions may be triggered based on the analysis of the biosignals including engaging the person, generating alerts, or adapting the vehicle control.
