Overhead Sliding Video Screen Monitor

2006-04-03
2006-01-1486
A novel longitudinally sliding overhead video screen monitor was developed to address consumer needs for vehicles equipped with rear seat entertainment and long length sunroofs. Long length sunroof openings in vehicles are causing engineers to mount video screen monitors in locations other than the overhead. Typically, they are mounted on the floor console or on the back of front seat head restraints. Floor console mounted video screen monitors generally do not provide a comfortable viewing distance or angle for second and third row occupants. Head restraint mounted video monitors cause issues with seat shake and two monitors adds to the vehicle cost unnecessarily. The mountable sliding video monitor assembly comprises of a video display screen, brackets for mounting the monitor, a pair of tracks that are movable with respect to each other, a series of ball bearings, and a roof mounting bracket. The inner main track is adapted for mounting the pair of tracks to the vehicle.

A Design Tool for Producing 3D Solid Models from Sketches

A novel design tool that produces solid model geometry from computer-generated sketches was developed to dramatically increase the speed of component development. An understanding of component part break-up and section shape early in the design process can lead to earlier part design releases. The concept provides for a method to create 3-dimensional (3D) solid models from 2-dimensional (2D) digital image sketches. The traditional method of creating 3-dimensional surface models from sketches or images involves creation of typical sections and math surfaces by referencing the image only. There is no real use of the sketch within the math environment. An interior instrument panel and steering wheel is described as an example. The engineer begins with a 2-dimensional concept sketch or digital image. The sketch is scaled first by determining at least three known feature diameters.

“Multi Vector” Field of View Design Tool

A multi vector design tool to accurately predict instrument panel obscuration was developed to insure that critical legal displays in vehicles are not obscured. The concept provides for a computer generated light source shaped to replicate the human eyes. The light source is then projected onto a 3D math based arrangement and the resultant shadows are visible on the instrument panel surface and its displays. Design studios require criteria for the placement of the instrument cluster gages and displays, various controls, switches, and steering column stalks before an interior theme can be completed. Therefore, instrument panel obscuration and visibility must be determined early in the design process. The obscured areas are a function of the instrument panel surface, steering wheel rim, hub, spokes, and the location of the driver's eyes. This light source method allows engineers and designers the ability to quickly determine obscured areas.

A Novel Design Concept of a Lateral Sliding Bucket Seat on Roller Mechanisms

A novel lateral sliding vehicle bucket seat was developed to address consumer needs for improved facile access to third row seats in minivans and sport utility vehicles. The concept provides for a second row bucket seat to slide laterally across a vehicle floor by roller mechanisms that roll across steel rails that transverse the vehicle floor. The system consists of two T-section type steel rails mounted parallel to each other at a distance equal to the seat riser support attachment features. The seat risers contain a roller mechanism that enables contact with the cylindrical portion of the steel rails. Each steel rail contains rectangular openings spaced appropriately to allow the seat latching mechanisms to engage securely. The seat riser supports at the rear include a releasable clamping mechanism hook that engages and disengages into the rectangular openings of the steel rails.
