The seat automatic arrangement method and apparatus have an advantage that it is possible to automatically arrange seats in the vehicle into the seat-facing mode through remote control, and it is possible to prevent interference when moving the seats by arranging the seats in accordance with priority when arranging the seats into the seat-facing mode, thereby being able to more smoothly arrange the seats into the seat-facing mode in an autonomous driving vehicle.

Abstract: 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.

Abstract: A pre-active safety seat system applied to the vehicle implements a method for improving a pre-active safety seat speed, which confirms a risk region by matching a recline angle, a slide movement position, and a cushion tilt angle, which are detected from each of a plurality of sensors of a multi-seat sensor in a risk collision situation detected by a vehicle environment sensor of an ADAS, with a seat safety map, and combines and simultaneously controls a plurality of motors of a multi-seat motor configured for a seat target posture of a seat for converting the risk region into a safety region, by a controller, shortening a pre-active safety seat (PSS) required time of a seat target posture in the pre-active safety seat (PSS) operable section before collision of the vehicle from a risk detection.

Abstract: A dual gear type recliner device includes a recliner device having a hinge structure applied to an intermediate section of a seat and configured to form a fixed end hinge point with a seatback frame of a seatback and form a free end hinge point with a cushion frame and configured to impart movements of folding and unfolding to the seatback. The dual gear type recliner device further includes a controller configured to output motor control signals to a cushion motor and a seatback motor and to generate the movements of the folding and the unfolding. Therefore, two drivers are integrated into one device to improve the degree of freedom in designing an outer circumference of the seat and built in a gear box to perform a large angle adjustment so that a back table mode and a leg rest mode can be easily implemented.

Abstract: A system for reducing driver fatigue in a seat includes an electric reclining device configured to recline a seat back, an electric extension device configured to move an extension unit formed at a front end part of a seat cushion forward and backward, an air cell device including a plurality of air cells installed in the seat back to be expandable, and a controller configured to control driving of the reclining device, the extension device, and the air cell device in a designated driving pattern to implement a driver fatigue reduction posture of the seat.

Abstract: A Pre-Active Adjustment Safety control method includes: determining whether a possibility of collision exceeds a predetermined value based on sensing information received from at least one of a front sensor, a lateral sensor or a rear sensor; determining a position of a seat and an angle of a seat back when the possibility of collision exceeds the predetermined value; and controlling the seat to a predetermined state when at least one of the position of the seat or the angle of the seat back is not in the predetermined state.

Abstract: A polyurethane filter foam is provided herein. The polyurethane filter foam may have improved permeability by having both a small cell and a large cell in a range for maximizing the opening property of the foam. In some instance, this is achieved by specifically configuring and foaming a composition of polyether polyol and methylene diphenyl diisocyanate (MDI) to manufacture the polyurethane foam. The polyurethane foam of the present invention can be manufactured without performing a reticulation process.

Abstract: 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.

Abstract: A seat cushion extension apparatus includes an extension motor supported on a cushion frame, an extension mounting bracket holding an extension cushion such that the extension cushion is displaceable forward and backward on a seat cushion, and a power transmission unit connecting between the extension motor and the extension mounting bracket. The power transmission unit receives power from the extension motor and moves the extension mounting bracket forward and backward. A slide device is coupled with the extension mounting bracket, and supports the extension mounting bracket such that the extension mounting bracket is slidable forward and backward in the cushion frame. The front-back length of the seat cushion can be freely extended, and limitations in the thickness of a cushion pad or the like are removed.
