  • Patent number: 7866730
    Abstract: The present invention is a twinsheet door which includes a first door portion and a second door portion connected to the first door portion. The twinsheet door of the present invention is manufactured using a thermoforming process, during which a vacuum shapes the first door portion and the second door portion such that one or more closed sections are created when the first door portion is thermally bonded to the second door portion and simultaneously a vacuum is applied to form the first door portion and said second door portion. The closed section formed between the first door portion and second door portion provides additional strength and rigidity to the twinsheet door. Additionally, the forming of the closed section between the first door portion and the second door portion and the bonding between the first door portion and second door portion is achieved during a single manufacturing process.

  • Patent number: 7819460
    Abstract: The present invention is a serviceable fabric assembly for a convertible roof of a motor vehicle having a retainer connected to a fabric cover and slidably engaged within a channel formed in a first bow member. The first bow member has an upper panel and a lower panel configured to form the channel substantially along the longitudinal length of the first bow member. The channel is configured to laterally receive a compressible portion of the retainer which prevents the retainer from exiting the channel in a direction transverse to the longitudinal axis of the first bow member. A gap is formed near at least one end of the channel on the outboard side of the channel and is sized such that an operator can slide the retainer out of the channel through the gap for servicing and replacing the fabric cover without having to disassemble the first bow member.
