  • Vehicle side glass setting apparatus
    Patent number: 8096044
    Abstract: An apparatus for setting side glass in a convertible vehicle body, prior to assembly of a convertible top on the vehicle body, includes a fixture adapted to engage multiple convertible top locating points on the vehicle's header and rear deck-lid shelf. Sensors mounted on the fixture detect the position of the raised side glass relative to the locating points and provide relative position information to an assembly operator, for example, through use of LED arrays, whereby the assembly operator can quickly set the side glass to a target position with which to achieve a desired side glass engagement with the convertible top, upon subsequent assembly of the convertible top to the vehicle body.
