An apparatus for controlling a headrest for a vehicle seat includes: a headrest disposed at an upper side of a vehicle seat and that moves to an upper end or a lower end; a slider that moves the seat forward or rearward; a recliner that rotates the seat forward or rearward; a drive unit that operates the headrest, the slider and the recliner; a sensor unit connected to the drive unit and that detects a position of the headrest, a position of the slider and a rotation angle of the recliner; an input unit that receives an inputted operation instruction to operate the slider and the recliner from a user; and a control unit that controls the drive unit based on the inputted operation instruction and operates the headrest upward or downward in accordance with the detected position and the detected rotation angle.

An apparatus for controlling a rear-seat leg support for a vehicle seat includes: a rear-seat leg support disposed at a lower side of a vehicle seat and that performs an upward-downward rotational operation and a forward-rearward slide operation; a passenger seat that performs a forward-rearward slide operation and a forward-rearward reclining operation; a drive unit that operates each of the rear-seat leg support and the passenger seat; a sensor unit connected to the drive unit and that detects a rotation angle and a slide position of the rear-seat leg support or a slide position and a reclining angle of the passenger seat; an input unit that receives an inputted operation instruction to operate the rear-seat leg support or the passenger seat; and a control unit that adjusts the slide position of the rear-seat leg support.

A method of adjusting a vehicle seat support system is provided. In particular, the method includes receiving a user selection at an input device and detecting a mode type associated with the user selection. A plurality of seat support features disposed within a vehicle seat are then adjusted toward a support characteristic that corresponds to the detected mode type.

A method of controlling movement of a first component of a vehicle, the first component being a squab or a bulkhead of a rear seat of a vehicle seating arrangement. The method involves receiving a signal indicative of a state of a second component of the vehicle and receiving a request to move the bulkhead so that the seat is in a folded condition. The squab of the rear seat is moved into engagement with the bulkhead of the rear seat prior to moving the bulkhead; and movement of the bulkhead is commenced in accordance with the request and in dependence on the signal indicative of the state of the second component.

A method of controlling a seating arrangement of a vehicle, the seating arrangement comprising a rear seat including a deployable calf rest, the method comprising: receiving a signal indicative of a state of a component of a front seat positioned ahead of the rear seat; and controlling movement of the calf rest in dependence on the signal indicative of the state of the front seat component.

A method of controlling tilting movement of a headrest of a seating arrangement of a vehicle, the method comprising: receiving a request for tilting movement of the headrest; determining if the headrest is attached to the seat by checking for the presence of at least one electrical component that is located within the headrest; and operating a tilt motor to commence tilting movement of the headrest in response to the request only if the or each component is found to be present.

A seat drive device, wherein one of first and second operation restricting portions corresponding to one of first and second transmission members is movable within one of first and second notches corresponding to another of the first and second transmission members when the one of the first and second transmission members is rotated from an initial state where both of the first and second transmission members are not rotated, and the first and second operation restricting portions are arranged to interfere with each other when both of the first and second transmission members are simultaneously rotated.

An apparatus (101) for controlling an interior environment of a road vehicle (120) is disclosed along with a vehicle (120) including the apparatus, a method and a computer program (115). The apparatus comprises controller means (102) configured to control a seat adjustment means (103) for adjusting a configuration of a passenger seat (105) and control at least one parameter defining an interior environment of a road vehicle (120). The controller means (102) is configured to cause the seat adjustment means (103) to adjust the configuration of a passenger seat (105) to a predefined configuration and cause a first one of the parameters to be adjusted to a first predefined value, on receipt of a first signal from a user input means (104) indicating a user selection of a first mode.

Vehicular control method to avoid collisions in which a smartphone is coupled to the vehicle while in a vehicular compartment. Data is generated from vehicle-resident sensors about operation of the vehicle and transferred from the vehicle to the smartphone while the smartphone is coupled to the vehicle. A communications network with another vehicle is established using the smartphone and the data transferred from the vehicle to the smartphone and data from sensors on the smartphone is transmitted via the smartphone and established communications network to other vehicle, the data including data about location and movement of the vehicle. Then, while the smartphone is coupled to the vehicle, a vehicular operational function is controlled based in part on data transmitted using the smartphone and established communications network to cause movement of the vehicle to change in order to avoid a collision with the other vehicle.
