Portable desk for vehicles

Abstract

A portable office device is adapted for use with a seat in a vehicle to form a desk and includes positionable support members or legs that may be folded or pivoted into either an extended or a retracted orientation. The positionable legs enable the portable desk to be selectively positioned within a vehicle at an elevated height for use within the vehicle with the legs in the extended orientation, and with the legs in the retracted orientation, enables the portable desk to be readily transported by hand. The portable desk may further include a pivoting work surface member, various storage compartments, and a slot for receiving a seat belt to secure the portable desk to the vehicle seat.
