The first flexible sheet includes a second antenna unit and first contact portions formed on a first opposing surface. The second flexible sheet includes a detection unit and second contact portions formed on a second opposing surface. The first contact portions and the second contact portions become a state of contact by an external force based on the seating of an occupant, cause the second antenna unit to output a transmission signal to the detection unit, and cause the detection unit to output a detection signal to the second antenna unit.

Vehicular detector and vehicular detection system

A light emitting device includes a light emitter, a holding portion that slidably holds the light emitter inside a slide rail for a vehicle, and a light transmissive cover that covers the light emitter. According to a configuration, the cover of the light emitting device prevents a decrease in a communication performance of a signal transmission and reception device in which information on an electronic device is transmitted using an LED, as compared with a related art in which the communication performance decreases due to influence of scattering or shielding a light of the LED, the influence being caused by a grease which is heavily applied inside a slide rail of a vehicle and adheres to the LED.

Light emitting device

A slide device includes an upper rail to which a slide seat for a vehicle is attached, a slide rail to which the upper rail is slidably attached, a light emitter, and an attachment portion that attaches the light emitter to the upper rail. The attachment portion is attached to the upper rail such that the light emitter is arranged outside the slide rail. According to the slide device, since the attachment portion is attached to the upper rail such that the light emitter is positioned outside the slide rail, the light emitter does not move inside the slide rail to which a large amount of grease is applied, and a decrease in communication performance can be prevented.

Slide device and light emitting device for slide device

A communication system includes a seat unit mounted on a seat of a vehicle and operating by an electrical power supplied from a battery, and a vehicle unit that wirelessly communicates with the seat unit, and transmits a start command. The seat unit receives the start command in a standby state in which a power consumption is lower than a normal state, and then the seat unit switches from the standby state to the normal state. After that, the seat unit transmits an information on an electronic device mounted on the seat, in the normal state. According to the communication system, the seat unit switches from the standby state to the normal state, only when the vehicle unit transmits the start command. Therefore, battery life can be extended.
