Abstract
Abstract A roof door device of a motor vehicle is disclosed. The vehicle has a roof and a side door operable to close a side door opening. The roof has a roof side opening which is positioned above and merged with the side door opening. A roof door is pivotally connected to the roof to open and close the roof side opening. A guide rail is mounted on the roof at a position near the roof side opening. A slider is slidable in and along the guide rail. A pivotal arm has one end pivotally connected to the roof and the other end connected to the roof door. A link member has one end pivotally connected to the slider and the other end pivotally connected to the pivotal arm, so that a movement of the slider in and along the guide rail in one direction causes folding of the pivotal arm thereby closing the roof side opening with the roof door. A pin is connected to the pivotal arm. The link member has a holding recess. The holding recess catches the pin to achieve a latched condition of the pivotal arm relative to the link member when the pivotal arm is folded to lie parallel with the link member.

Independent Claim
221 words
In a motor vehicle having a roof and a side door operable to close a side door opening, a roof door device comprising: first means defining in said roof a roof side opening which is positioned above said side door opening; a roof door pivotally connected to said roof to open and close said roof side opening; a guide rail mounted on said roof at a position near said roof side opening; a slider slidable in and along said guiderail ; a pivotal arm having one end pivotally connected to said roof and the other end connected to said roof door; a link member having one end pivotally connected to said slider and the other end pivotally connected to said pivotal arm, so that a movement of said slider in and along said guide rail in a given direction causes folding of said pivotal arm thereby closing said roof side opening with said roof door; a first pin connected to one of said pivotal arm and said link member; and second means defining in the other of said pivotal arm and said link member a holding recess, said holding recess catching said first pin to achieve a latched condition of said pivotal arm relative to said link member when said pivotal arm is folded to lie parallel with said link member.
Claim 2
Dependent Claim
221 words
In a motor vehicle having a roof and a side door operable to close a side door opening, a roof door device comprising: first means defining in said roof a roof side opening which is positioned above said side door opening; a roof door pivotally connected to said roof to open and close said roof side opening; a guide rail mounted on said roof at a position near said roof side opening; a slider slidable in and along said guiderail ; a pivotal arm having one end pivotally connected to said roof and the other end connected to said roof door; a link member having one end pivotally connected to said slider and the other end pivotally connected to said pivotal arm, so that a movement of said slider in and along said guide rail in a given direction causes folding of said pivotal arm thereby closing said roof side opening with said roof door; a first pin connected to one of said pivotal arm and said link member; and second means defining in the other of said pivotal arm and said link member a holding recess, said holding recess catching said first pin to achieve a latched condition of said pivotal arm relative to said link member when said pivotal arm is folded to lie parallel with said link member.
