A vehicle door system includes doors with a door module attached to a hinge module, which is attached to the vehicle body. The door module includes a latch mechanism configured to engage a striker pin of the vehicle body, with a pawl that pivots to accommodate a misalignment with the striker pin during a door closing operation, with the latch mechanism shifting following engagement with the striker pin. A door check mechanism includes a permanent magnet and a steel plate. Activation of the permanent magnet shifts the steel plate from a closed position to an open position permitting the hinge module to move from a locked position. An interface between doors includes a primary and secondary seal each having a constant cross section, with filler pieces disposed between the door and the secondary seal along a portion of the interface.

A door leading edge sensor has: a door leading edge elastic member which is attached to a front end portion of a door in a door closing direction and in which a cavity extending in a direction intersecting with the closing direction is formed therein; and a linear pressure sensitive sensor that is attached to the door leading edge elastic member and is disposed along the extending direction of the cavity. The pressure sensitive sensor has an insulator tube having such an elasticity as to be deformed in accordance with an elastic deformation of the door leading edge elastic member and plural conductive members fixed to an inner surface of the insulator tube. The plural conductive members are in a non-contact state when the insulator tube is not deformed and are in contact with each other when the insulator tube is deformed.

A sliding door assembly includes a door frame with a top trim member, a bottom sill, and side jambs connected between the top trim member and the bottom sill, and a primary sliding panel secured in the door frame. The top trim member includes a track configured to support a weight of the primary sliding panel and prevent the primary sliding panel from coming off the track. Other features include an interlock mechanism to limit relative movement using multiple sliding doors and a brake mechanism to secure the doors in position when the door handle is released. A drop window includes features to accommodate for manufacturing tolerances and box frame assemblies that are out of square.

A leaf, of a sliding window or sliding door, has a top profile that is provided with at least one hardware component and which has a side profile perpendicular to the top profile, whereby the top of the top profile has a groove with undercut flanks extending in the longitudinal direction of the top profile, whereby the hardware component or hardware components is or are fastened to a first part of a connecting piece, whereby the first part has a shape that is at least partly complementary to the groove, the first part being held in the groove and locked in the longitudinal direction of the groove.
