An occupant posture adjustment device and a pedal device include a pedal adjustment mechanism that changes the inclination of a pedal with respect to a floor panel between a first driving state and a second driving state, and a controller that, in the first driving state, controls the pedal adjustment mechanism such that a back face of the pedal and the floor panel are separated from each other, and in the second driving state, controls the pedal adjustment mechanism such that the back face of the pedal and the floor panel come into contact with each other.

A vehicle occupant posture detection (OPD) system, including: a measuring device coupled to a seat back of a seat of a vehicle and adapted to determine an angle () between a Z-axis and a torso line of an occupant seated in the seat by measuring an angle of the seat back; a measuring device coupled to a seat bottom of the seat of the vehicle and adapted to determine an angle () between the Z-axis and a femoral line of the occupant seated in the seat by measuring an angle of the seat bottom; and means for receiving and using the determined values of and to determine an angle () between the torso line and the femoral line of the occupant seated in the seat and thereby characterize a posture state of the occupant seated in the seat.

A trim element having a trim panel that includes an inner face and an outer face and at least one support element extending over the inner face and protruding toward the outer face such that the trim panel marries at least part of the contour of the support element in order to form a support surface on the outer face. The support element can be positioned in a plurality of positions relative to the trim panel, which is deformable to marry at least part of the contour of the support element so that the support surface can be positioned in a plurality of areas of the outer face.

A trim element having a trim panel that includes an inner face and an outer face and at least one support element extending over the inner face and protruding toward the outer face such that the trim panel marries at least part of the contour of the support element in order to form a support surface on the outer face. The support element can be positioned in a plurality of positions relative to the trim panel, which is deformable to marry at least part of the contour of the support element so that the support surface can be positioned in a plurality of areas of the outer face.

Described are adjustable seats having a lower portion of a back rest attached to a seat frame having an upper frame and a lower frame. A pivot axis is positioned at an upper end of the lower portion of the back rest, and an upper portion of the back rest is pivotally attached to the pivot axis. The location of the pivot axis is configured to be positioned below a person's shoulders when the person is seated in the adjustable seat. The upper portion of the back rest is also pivotally adjustable relative to the lower portion of the back rest. A seat pan having a front portion pivotally coupled to a rear portion can be attached to the upper frame. An actuation mechanism is configured to simultaneously control a vertical height of the upper frame and a rotational position of the front portion of the seat pan.

An adjustment assembly or mechanism that permits adjustment of the height and angle of tilt of a vehicle seat includes front and rear latch gears with multiple cogs corresponding to discrete angular positions of the latch gears and consequently discrete heights of the front and rear of the adjustment assembly. The front latch gears pivot about a fixed pivot axis while the rear latch gears pivot about a sliding pivot axis to accommodate tilt angles for the seat. Torsion springs bias the four latch gears to a maximum rotation or pivot position in which the respective ends of the seat are at their highest vertical position. A spindle engages the cogs of the latch gears to hold the latch gears in a particular discrete angular position. Separate front and rear manual actuation levers at the front of the seat can be lifted to release a respective front and rear spindle from a particular cog and allow the driver to adjust the seat position. The independent front and rear adjustment mechanisms allow the driver to place the seat in a wide range of heights and tilt angles, including forward and rearward tilt angles.

A seat adjustment mechanism for a vehicle seat is provided. The mechanism may have a number of first pairs of rails, where each first pair of rails has an upper rail and a lower rail. The mechanism may also have a number of second pairs of rails with a substantially same acting direction as the number of first pairs of the pairs.

A power seat device is configured to acquire a target associated position of a tilted position, corresponding to a current position of a seatback for allowing the seatback to reach an end position in a reclining range, and a seat to reach an end position in a tilting range simultaneously. Outputs of a reclining motor and a tilting motor are adjusted so that the tilted position coincides with the acquired target associated position.

The time required to complete current-to-target state transitions of a plurality of movable portions constituting a seat is shortened. A seat unit 1 includes an occupant support portion S1, a plurality of movable mechanisms respectively moving a plurality of parts constituting the occupant support portion S1, and an ECU 40 controlling respective operations of the plurality of movable mechanisms. The ECU 40 causes each of the plurality of movable mechanisms to undergo a transition from a current state to a target state and the plurality of movable mechanisms have a first movable mechanism requiring a longest time for the transition. The ECU 40 causes the transitions of the plurality of movable mechanisms other than the first movable mechanism to be completed by completion of the transition of the first movable mechanism from the current state to the target state.

A vehicle interior system including a first seat assembly, disposed within a vehicle cabin, a first sensor, a second sensor, and a controller is provided. The first and second sensors may each be disposed within the vehicle cabin. The first sensor may be configured to obtain first signals indicative of a positioning of an obstacle within a predetermined coordinate system. The second sensor may be configured to obtain second signals indicative of a positioning of the first seat assembly within the predetermined coordinate system. The controller may be configured to receive the signals from the first sensor and to map a portion of the obstacle based on the first signals and relative to a portion of the first seat assembly within the predetermined coordinate system.
