Abstract
Abstract The present invention provides a portable computer having a palm rest integrated therein that allows the user to maintain a wrist-neutral position when using the portable computer. The portable computer comprises a computer chassis having a side wall adjoining a bottom that forms a footprint of the chassis, a keyboard positioned toward a rear end of the chassis, and a cover member covering a portion of an interior of the chassis. The portable computer further includes a palm rest integrated into the structure of the portable computer's chassis. The palm rest is comprised of a palm support that has front and rear ends and that is pivotable with respect to the chassis between a covering position and an elevated first palm support position. The palm support is pivotable about a hinge, that couples the palm support to the chassis. The palm rest further includes an adjustable extension structure having a first end coupled to the palm support and a second end coupled to a wall of the chassis. The adjustable extension is pivotally coupled to the palm support adjacent a front end of the palm support.
