Advantages

Some advantages of our Retractable Door architecture include:
- Significant improvement in strength, stiffness and lightness of overall structure.
- Applicable to all traditional and modern construction materials.
- Greater safety in door operation and vehicular crash worthiness.
- Access to occupant and/or their escape greatly enhanced is serious crash situations.
- Convenience of power operation.
- Moving doors will stop and reverse if foreign object detected.
- Vehicle floor and belly pan form a box-like structure which greatly enhances body stiffness and strength.
- New geometry of inner and outer sills also contributes to overall structure efficiency and weight savings.
- Passenger doors can be opened and closed safely from driver’s seat via window lift type activation.
- Door cuts need not be absolutely vertical.
- Cannot be ‘parked in’.
- Side mirrors remain in place when door is opened enabling continued observation of traffic from behind.
- Drop door does not swing out endangering other road users or pedestrians.
- No door ‘dings’.
- Less parking or garage space required.
- Compact outer sill reduces ’step over’ during entry and egress.
- Drop door need not be stressed for multiple slams during its life cycle.
- It may be constructed as a modular component with the door frame designed to reintegrate structurally with the main vehicle body.
- 2, 3, 4, and 5-door applications possible for sedans, coupes, wagons, hatchbacks, convertibles, crossover vehicles, SUV’s, trucks, and vans, whether equipped with front, rear or all-wheel drive.
- Converted vehicles for the physically challenged.
- Special vehicles for domestic services and the military.
