The present invention provides a cushion pad with improved durability without feeling of a foreign object.

The present invention thus provides a system for detecting a deformation of a cushion pad, comprising; the cushion pad comprising a matrix layer, in which electroconductive or magnetic filler is dispersed, and a soft polyurethane foam including the matrix layer incorporated therein, and a detecting portion that detects an electric or magnetic change caused by a deformation of the cushion pad, wherein the matrix layer has a hardness lower than the soft polyurethane, and it production method.

The present invention relates to a measurement arrangement for detecting an occupancy of a motor vehicle seat arrangement with at least one seat, which comprises a sensor arrangement with at least one sensor (10) for detecting a deformation of a lower side (21) facing away from the seating surface or of a force loading by a lower side (21) facing away from the seating surface of a seat cushion (20) of at least one seat of the motor vehicle seat arrangement, which is fastened on a structural element (40) of the motor vehicle.

A motor vehicle with a seat unlocking system includes a seat with a seat part and a back part secured to a body at an attachment, an airbag, and an actuator for releasing the attachment of the seat to the body. Following activation of the actuator, the attachment between the seat and the body is disconnected such that the seat is moveable relative to the body. A control unit is configured to activate the actuator following an accident exclusively in the case of an opened airbag and exclusively with the motor vehicle at a standstill.

A seat with an adjusting mechanism for selectively changing a contour and firmness of the seat. A force/pressure sensor is arranged between the contour of the seat which is in contact with the occupant, and the adjusting mechanism. The force/pressure sensor measures the actual force/pressure with which the occupant presses upon the seat, and which force/pressure is adjustable by the respective adjusting mechanism. A control unit stores a desired force/pressure value for the seat, and controls the adjusting mechanism to drive the actual force/pressure towards the desired force/pressure. The seat also has an operator interface which receives input from an operator. The control unit has a manual mode where the adjusting mechanism is only controlled by the operator interface. The control unit in the automatic mode records the actual value from the force/pressure sensor when the operator adjusts the seat through the interface. The control unit then sets the desired force/pressure to the present value of the force/pressure sensor. Once the operator is finished changing the adjusting mechanism, the control unit continues in automatic mode and performs any changes to the adjusting mechanism to drive the actual force/pressure from the force/pressure sensor for the value of the new desired force/pressure.

Embodiments of the present disclosure a computer-implemented method comprising receiving sensor data from one or more vibration sensors that are embedded within a seat, where the sensor data includes data associated with speech by an occupant of the seat, and at least one of processing, transmitting, or storing the sensor data based on the data associated with the speech.

The invention relates to a vehicle seat, in particular for commercial vehicles, comprising a seat part and a backrest, wherein the vehicle seat has an apparatus for detecting seat occupancy, which comprises at least one first detection device and at least one second detection device, wherein the at least one first detection device is suitable and intended for detecting occupancy of the seat part, wherein the at least one second detection device is suitable and intended for detecting occupancy of the backrest.

A sensor arrangement for capacitive detection of an object, including: an electrode arrangement having a heating element as an electrode; a detection device providing a detection signal to a sensor electrode and capacitively detecting the presence of an object near the sensor electrode; a high-side switch connected between a heating power source having a first potential and the heating element; a low-side switch connected between the heating element and a second potential; and a gate controller closing the high-side switch and low-side switch in a heating mode and opening the high-side switch and low-side switch in a detection mode. A decoupling MOSFET is connected between the high-side switch and heating element. The gate controller closes the MOSFET in the heating mode and opens the MOSFET in the detection mode. During the detection mode, the decoupling circuit provides a third potential at a first node between the high-side switch and MOSFET.

The present invention provides a cushion pad with improved durability without feeling of a foreign object.

The present invention thus provides a system for detecting a deformation of a cushion pad, comprising; the cushion pad comprising a magnetic elastomer in which magnetic filler is dispersed in an elastomer and an arithmetic average roughness (Ra) is 0.5 to 10.0 m, and a soft polyurethane foam which is integrated with the magnetic elastomer by adhesion, and a magnetic sensor that detects a magnetic change caused by a deformation of the cushion pad. The present invention also provides a production method thereof.

A system and method for warning a third party about a temperature condition for a forgotten occupant based upon an estimated temperature. The system and method include retrieving a weather forecast for an area in which the vehicle is located and estimating a future temperature of the passenger compartment in response to determining that the drive system of the vehicle has been shut off and that the driver has exited the vehicle, the method determines whether an occupant remains in the passenger compartment of the vehicle. The future temperature of the passenger compartment is a temperature of the passenger compartment of the vehicle after a lapse of a predetermined time period. In response to determining that the estimated future temperature is outside of the predetermined temperature range send a warning to the computing device.

A cushioned device configured to prevent an occupant of a vehicle from being left unattended. The device includes a cushioned pad with a pressure sensor, a dongle, and an optimal application for receiving a pressure signal detected by the cushioned device. The application and dongle capable of generating an audible noise and associated notifications when a predetermined distance between the cushioned portion and the dongle and/or application is too great indicating that the object on the cushioned pad is now unattended. Accordingly, this system utilizes the proximity of companion devices and detected pressure signal to determine unattended occupancy in a confined space.
