摘要

Arrangement for obtaining information about an occupying item of a seat having a seat portion and a back portion. The arrangement including a distance-determining sensor arranged in the back portion of the seat and enabling the determination of the distance between the occupying item and the back portion, an angle sensor arranged in connection with the seat for detecting an angle between the back portion and the seat portion, and a seat displacement sensor arranged in connection with the seat for detecting longitudinal displacement of the seat. Additional sensors systems can be used to provide additional information about the occupying item, such as a weight sensing system arranged in connection with the seat for measuring weight applied to the seat by the occupying item and one or more wave-based, capacitance or electric field sensor systems arranged to provide information about the position of the occupying item. A component adjustment system may be coupled to the arrangement and adjust a component operative with respect to the occupying item based in part on the information about the occupying item obtained by the arrangement. The component may be a steering column or a pedal.
