A respiration signal of a seated person is detected with high accuracy by using a vehicle seat that includes a seat cushion; and a sensor detecting a pressure signal from a load applied from a seated person. The sensor is provided to be along an edge of a contact portion between the seat cushion and buttocks of the seated person. The sensor transmits the detected pressure signal to an arithmetic operation device of the seated person. In a respiration measuring device, the arithmetic operation device computes the detected pressure signal detected by the sensor to obtain a respiration signal of the seated person.

An occupant detection system includes a controller, a sensing electrode, and a shield electrode, the electrodes disposed in a vehicle seat. The controller is electrically coupled to the sensing electrode and shield electrode by a sensing circuit. The controller is configured to send an input signal to the sensing electrode, the shield electrode, or both and measures current, impedance, or capacitance values to determine the presence of an object on the seat, to classify the object, or both.

A vehicle seat includes a frame member provided on a floor of a vehicle, a seat part such as a seat cushion detachably attached to the frame member, a mechanical connector device provided on the frame member and the seat part for detachably attaching the seat part to the frame member, and an electric connector device provided on the frame member and the seat part for electrically connecting an electric component provided on the seat part to an electric component provided on the frame member.

A system comprising: a heater located within a steering wheel and a heater located within a vehicle seat; wherein the steering wheel is a first plate and the vehicle seat is a second plate and a shift in a signal is monitored from the first plate, the second plate, or both so that a presence and absence of an occupant is detected, and wherein the heater in the steering wheel and the heater in the vehicle seat are a sensor.

An occupant sensor having a switching element, which comprises a top carrier layer and a bottom carrier layer separated by a spacer. The spacer has an opening defining an active zone in which the carrier layers may be brought together in response to a force acting on at least one of them. The switching element includes a first electrode and a second electrode arranged within the active area between the carrier layers such that an electrical contact is established between the first and second electrodes if the carrier layers are brought together. The occupant sensor includes a decoupling layer arranged on a top side of the switching element such that the decoupling layer covers the top carrier layer in the region of the active area. The decoupling layer and switching element are laterally displaceable with respect to each other in the region of the active area.

The seat heater control device is provided for a vehicle including a vehicle body, a vehicle seat and a seat heater. The seat heater control device includes: an electrostatic sensor provided in the vehicle seat and configured to measure capacitance between the electrostatic sensor and the vehicle body; and a controller configured to control an operation and/or an operational temperature of the seat heater, based on a measured value of the electrostatic sensor. The controller is configured to cause the seat heater to operate at a relative higher temperature when the measured value of the electrostatic sensor is higher than a first threshold and lower than a second threshold. The controller is configured to cause the seat heater to operate at a relative lower temperature when the measured value of the electrostatic sensor is higher than the second threshold.

To provide a seat system that allows the information of the user seated in the seat to be acquired by another user, a seat system includes: a seat main body; at least one sensor provided in the seat main body; a control device for processing a signal from the sensor; and a first user interface communicating with the control device and notifying information based on a signal from the control device. Preferably, the sensor acquires information obtained from a seated person who is seated on the seat main body. Preferably, the seat system includes a camera for capturing an image of the seated person who is seated on the seat main body, and the control device causes the first user interface to display the image captured by the camera.

A system comprising: a heater located within a steering wheel and a heater located within a vehicle seat; wherein the steering wheel is a first plate and the vehicle seat is a second plate and a shift in a signal is monitored from the first plate, the second plate, or both so that a presence and absence of an occupant is detected, and wherein the heater in the steering wheel and the heater in the vehicle seat are a sensor.

A device for detecting the position of a person on a cushion includes at least two moisture sensors located in the cushion.

A vehicle child safety seat alert system for alerting a caregiver if a child has been left behind in a vehicle. The vehicle child safety seat alert system includes a seat component configured to determine whether a child is sitting on the seat component, identify a Bluetooth signal from the target vehicle and use that signal to determine when the vehicle is turned off, and duplicate an RF signal that actuates the vehicle's sensory alarm system so as to be able to selectively actuate the vehicle's sensory alarm system. In use, with the seat component placed under a child's seat, whenever the vehicle has been turned off, if a child is still on top of the seat component, the seat component will wirelessly actuate the vehicle sensory alarm system after a predetermined period of time.
