Abstract: A seat belt apparatus includes a main belt, a first buckle that is disposed on an extended part of the main belt and that can be buckled and fastened to a second side of the vehicle seat corresponding to a waist on the other side of the passenger, and an auxiliary belt extending from a second part of a backrest of the vehicle seat corresponding to an underarm of the passenger, where the second part is lower than the first part. The apparatus is configured such that in the event a body of the passenger slides forward relative to the vehicle seat, the underarm of the passenger is blocked by the auxiliary belt.

Abstract: The present invention provides a radio frequency channel, including: a first antenna, a low noise amplifier, a power divider, at least two first single-pole, n-throw switches, at least four first filters, and at least two first radio frequency chips. The power divider divides a received radio frequency signal into two first radio frequency sub-signals, and transmits the two first radio frequency sub-signals to the at least four first filters, where the at least four first filters correspond to at least four filtering bands and the at least four first filters may cover frequency bands involved in at least six carrier aggregation CA technologies, the at least four first filters filter the first radio frequency sub-signals, and the at least two first radio frequency chips process the filtered first radio frequency sub-signals.
