The present invention discloses a rotation device for a vehicle seat. The device includes a fixed disc, a lower ball assembly, a movable disc, an upper ball assembly, and a platen successively arranged from bottom to top. A first lower circular track is formed on the fixed disc. A first upper circular track and a second lower circular track are formed on the movable disc. A second upper circular track is formed on the platen. A diameter of a first arcuate envelope line of the first lower circular track that is in contact with a lower ball and a diameter of a second arcuate envelope line of the first upper circular track that is in contact with the lower ball are both equal to a diameter of the lower ball, and a height of the first arcuate envelope line and a height of the second arcuate envelope line are 0.8 times the diameter of the lower ball. A diameter of a third arcuate envelope line of the second lower circular track that is in contact with an upper ball and a diameter of a fourth arcuate envelope line of the second upper circular track that is in contact with the upper ball are both equal to a diameter of the upper ball, and a height of the third arcuate envelope line and a height of the fourth arcuate envelope line are both 0.8 times the diameter of the upper ball. By means of the present invention, a smooth rotary operating force can be achieved, and a service life of the rotation device can be properly prolonged.

An apparatus and a method for controlling an interior of a vehicle are disclosed. The apparatus for controlling the interior of the vehicle may include an interface configured to receive, at predetermined cycles, information on at least one of video of an inside of the vehicle collected by a camera or sound of the inside of the vehicle collected from a microphone, and a processor configured to determine a relationship between passengers in the vehicle based on the information, and control the interior of the vehicle based on the relationship between the passengers. When determining the relationship between passengers, a passenger relationship estimation algorithm used may be a neural network model generated through machine learning, and may be stored in a memory in the apparatus for controlling the interior of the vehicle, or may be provided via a server in an artificial intelligence environment through a 5G network.

Provided are methods for automatically adjusting a vehicle seating area based on the characteristics of a passenger. In an example method, a seat adjustment system of a vehicle receives sensor data representing at least one measurement of a user exterior to the vehicle, determines at least one characteristic of the based on the sensor data, determines at least one modification to a seating area of the vehicle based on the at least one characteristic of the user, and causes the seating area to be adjusted in accordance with the at least one modification. Systems and computer program products are also provided.

Proposed are a seat side bolster apparatus and a control method thereof. The seat side bolster apparatus of the disclosure includes a driving unit, which is provided under a foam pad of a seat cushion, is moved upwards and downwards by operation of an actuator, and presses the foam pad upwards when moving upwards, and a covering bracket, which is connected to the driving unit so as to be moved upwards and downwards together with the driving unit and to which an end of a covering enveloping the foam pad of the seat cushion is fixed.

Disclosed is an apparatus for moving a motor-operated seat rail, the apparatus including a lower rail coupled to a vehicle body and located on a lower surface of a floor, an upper rail configured to integrally move with a seat along the lower rail, a lead screw located inside the lower rail, a drive unit located in the upper rail, a gear box located in the lead screw, the gear box receiving driving force from the drive unit to integrally move with the upper rail along the lead screw, and a drive transmission unit located between the drive unit and the gear box.

An adjustable sofa-bed assembly for use within a vehicle such as a van or RV. The sofa-bed includes a seat portion, a back portion, and either a permanently fixed base or a removable leg portion which allows the legs to be installed into the vehicle prior to installing the seat and back portions to allow for additional elements to be installed beneath the sofa-bed, such as power elements for a powered sofa-bed assembly or for other equipment. The sofa-bed can be transformed from a sofa configuration with an upright back portion to a bed configuration with a laid-flat back portion. When in the bed configuration, the seat portion and back portion are aligned such that there is no gap between the two portions and the two portions lie completely flat, forming a complete bed assembly.

A user destination is identified based on received location information from a user. A first seat in a vehicle is assigned to the user based on the user destination. At least one of the first seat and a second seat in the vehicle is moved upon user entry until a distance between the first seat and the second seat is greater than a distance threshold.

A vehicle seat control device including a control unit that, in a case in which at least one user has declared in advance a desire to board a self-driving vehicle having a plurality of seats that are switchable between a first state in which a user is able to sit down, and a second state that impedes a user sitting down, switches a same number of seats as a number of the at least one user to the first state before the at least one user boards the vehicle.

A seat control device is configured to control an operation of an electric seat including a seat portion and a backrest portion. The seat control device includes: a first control unit configured to control an operation of the seat portion; a second control unit configured to control an operation of the backrest portion; and a pinching detection unit. In a case in which the pinching detection unit detects pinching during operations of both the seat portion and the backrest portion, the first control unit performs control to bring the seat portion into a pinching- free state in accordance with a direction of the operation of the seat portion before the pinching occurs, and the second control unit performs control to bring the backrest portion into a pinching-free state in accordance with a direction of the operation of the backrest portion before the pinching occurs.

A seat control device is a control device of an electric seat. The seat control device includes: a control unit configured to control an operation of the seat; a pinching detection unit configured to detect pinching of an object occurring while the seat is moving; and a seating detection unit configured to detect whether or not an occupant is seated on the seat. In a case in which the pinching detection unit detects pinching and the seating detection unit does not detect seating of the occupant, the control unit moves the seat in a reverse direction by a predetermined amount. In a case in which the pinching detection unit detects pinching and the seating detection unit detects seating of the occupant, the control unit moves the seat in the reverse direction by an amount smaller than the predetermined amount.
