The present invention discloses a seat misuse alarm device (100). The seat misuse alarm device (100) includes a base (1), a seat (2), an alarm mechanism (3), and a switch triggering device (4). The seat (2) has a forward facing position and a rearward facing position relative the base (1). The alarm mechanism (3) has a switch (31). The switch triggering device (4) triggers the switch (31) to close for making the alarm mechanism (3) send out an alarm when the seat (2) is located at the forward facing position relative to the base (1).

A control circuit according to the application is suitable for controlling an tilt angle of a carrier, wherein the control circuit includes: a sensor module, sensing a current angle of the carrier with a horizontal plane; a drive module, driving and adjusting the tilt angle of the carrier; and a control module, electrically connected to the sensor module and the drive module to output a control signal based on the current angle of the carrier with the horizontal plane, so as to dynamically adjust the tilt angle of the carrier. The application also provides a child safety seat and a method for adjusting the tilt angle between the seat and the base of the child safety seat.

A vehicle detects a rotation angle of a seat, controls activation of a first type of roof airbag module provided in a central portion of a headlining and located at a side of the seat when the detected rotation angle of the seat is greater than a first reference angle and less than or equal to a second reference angle, controls activation of the first type of roof airbag module and a second type of roof airbag module provided in the central portion of the headlining and provided at a rear of the seat when the detected rotation angle of the seat is greater than the second reference angle and less than or equal to a third reference angle, determines whether a collision with an obstacle has occurred during traveling, and deploys and expands the activated airbag module when determining that the collision with the obstacle has occurred.

A vehicle seat for a motor vehicle includes a seat bottom and a seatback displaceable relative to one another. A seat positioning system has an actuator for displacing one of the seat bottom and the seatback toward the other of the seat bottom and the seatback. The system further includes a position sensor for generating a seat position signal indicative of a position of one of the seat bottom and the seatback relative to the other of the seat bottom and the seatback. The system further includes a controller for generating an activation signal in response to the controller determining that the position is above the position threshold. The actuator displaces one of the seat bottom and the seatback toward the other of the seat bottom and the seatback in response to the actuator receiving the activation signal from the controller.

A safety device for a motor vehicle seat comprising: a seat, an electric motor for moving the seat or a part of the seat, and a control device configured for measuring/detecting at least one operating parameter of the motor among the voltage and/or the current of the motor and/or the speed of the motor, when the seat or the part of the seat is moving along a movement path when actuated by the motor, the control device being configured for ensuring that the motor is stopped when the at least one parameter of the current measurement crosses at least one threshold.

A car sickness inhibition device includes: a memory and a processor connected to the memory, the processor being configured to: acquire an acceleration a in a front-rear direction of a vehicle or angles of inclination θ of the head and upper body of an occupant sitting in a seat of the vehicle; and by using expression θ>tan.sup.−1(a/g).Math.(1), where g denotes gravitational acceleration, obtain from the acquired acceleration a an angle of inclination θ0 with which car sickness is inhibited, or obtain an acceleration a0 with which car sickness is inhibited.

There is provided a technique by which posture changing can be given to an occupant while the forward shift of his/her hip portion is prevented. A seat for vehicle includes a seat cushion, and a seat back coupled to the seat cushion, and the seat back includes a posture changing mechanism having a back face supporting mechanism. There is provided a technique by which a fatigue reduction operation using the posture changing mechanism includes a) moving the back face supporting mechanism set to a position of a lumbar spine portion of an occupant from a first position state to a rear direction side and setting the back face supporting mechanism to a second position state, and b) thereafter, moving the back face supporting mechanism stepwise to a front direction side from the second position state to the first position state.

In order to prevent distortion of slide rails caused by an urging force generated by an urging member in a vehicle tumble seat, a vehicle seat is capable of taking a stowed position in which a seat back is folded onto a seat cushion and the seat cushion together with the folded seat back is rotatably lifted away from a floor, and the vehicle seat is configured to include a support member coupled to the floor; a rotating member rotatably supported by the support member via a support shaft extending in a right-left direction; a lower rail extending in a front-rear direction and coupled at an end to the rotating member so as to be extend literally offset relative to the support shaft; an upper rail slidably supported by the lower rail and coupled to the seat cushion; a coupling device provided at a second end of the lower rail on a side toward the support shaft and capable of selectably connecting to the floor; and an urging device extending the front-rear direction and having one end coupled to the support member and a second end coupled to the lower rail on the side toward the support shaft side, wherein the urging device is configured to be expandable and contractible in a longitudinal direction thereof so as to urge the seat cushion in such a direction as to rotate about the support shaft away from the floor.

Aspects of the disclosure relate to determining and responding to an internal state of a self-driving vehicle. For instance, an image of an interior of the vehicle captured by a camera mounted in the vehicle is received. The image is processed in order to identify one or more visible markers at predetermined locations within the vehicle. The internal state of the vehicle is determined based on the identified one or more visible markers. A responsive action is identified action using the determined internal state, and the vehicle is controlled in order to perform the responsive action.

The present invention is an elevated vehicle system. The preferred embodiment of the present invention has a steering wheel, an engine, a plurality of seats, a plurality of windows, and a plurality of wheels. The steering wheel rotates to turn the plurality of wheels. The engine has a transmission and power system. The power system is a battery that provides power to various components within the present invention. The plurality of seats has a seatbelt, a hydraulic lift, and a plurality of buttons. The seatbelt is a flexible, nonelastic material that holds a passenger in their seat. The hydraulic lift is a mechanical system that lifts and lowers the seat. The plurality of buttons is used to control the height positioning of the seat. Additionally, a sensor is used to control the raising and lowering of the seats.
