A headrest of a vehicle seat includes: a headrest frame that is formed of at least one plate material and is fixed to a seatback frame of the vehicle seat; a pad that covers the headrest frame; and a skin that covers the pad. A contact section is provided at the lower part of the headrest frame, said lower part being located on the seatback-frame side, and the contact section is located closer to the rear surface of the headrest than the upper part of the headrest frame is, said upper part being located on the opposite side to the seatback-frame side.

Headrest and vehicle seat

In transmission of data to a receiving terminal, loss of packets is prevented even when the processing capacity of the receiving terminal is low. A necessity-of-adjustment determining module determines whether a receiving terminal, specified as the destination of each transmission unit of packets received from a packetizer module, needs adjustment of transmission intervals, on the basis of a necessity-of-adjustment table which is a list of receiving terminals which need adjustment of transmission intervals. If it is determined that the receiving terminal needs adjustment of transmission intervals, the one transmission unit of packets is transferred to a transmission interval adjustment module. The transmission interval adjustment module adjusts the packet-to-packet transmission intervals for the received one transmission unit of packets and transmits the packets included in the one transmission unit of packets, packet by packet, at the adjusted transmission intervals over a network via a transmission module.
