Patent number: 8449025Abstract: Aspects of the invention relate to a roof assembly for a vehicle having a roof opening in its fixed roof. It comprises a stationary part having longitudinal guides positioned on either side of the roof opening. A closure is movable at least between a closed position closing the roof opening and an open position in which the closure is at least partly opening the roof opening. A closure operating mechanism is provided for opening and closing the closure, and is sliding in said longitudinal guides when opening and closing the closure. The longitudinal guides each comprise at least a drain channel and a water drainage member for draining water from said longitudinal drain channel to a water drainage hose. Each water drainage member communicates with the respective drain channel on one end, and connects to the corresponding water drainage hose on its opposite end to form a drain. A sieve member for catching debris but allowing water to run through is provided in the drain upstream of said water drainage member.Type: GrantFiled: January 24, 2011Date of Patent: May 28, 2013Assignee: Inalfa Roof Systems Group B.V.Inventors: Egbert Boersma, Michael Cornelis Anthonius Relouw, Danny Wilhelmus Arend Kok, Leonardus Gerardus Maria Verbeek

Patent number: 6942285Abstract: A vehicle has a roof assembly for opening an opening in its fixed roof. The roof assembly includes a frame attached to the vehicle roof and a panel which is movably supported by said stationary part and which can be adjusted by an adjusting mechanism including a driving slide. The panel is movable between a closed position for closing the roof opening, and an open, rearward position for being at least partially above the roof behind the roof opening, in which the roof opening is at least partially released. The frame is fitted with at least one front longitudinal guide track extending at least along the roof opening, whereas a rear longitudinal guide track is mounted at least substantially rearward of the roof opening.Type: GrantFiled: January 23, 2003Date of Patent: September 13, 2005Assignee: Inalfa Roof Systems Group B.V.Inventors: Peter Christiaan Leonardus Johannes Manders, Egbert Boersma

Patent number: 6652023Abstract: An open roof construction for a vehicle having a roof opening includes a closure element for the roof opening, which is driven by a driving element. The closure element can be locked in at least one position with respect to the vehicle, whilst the driving element can be disconnected from the closure element in that position for the purpose of driving another element. A coupling arm is pivotally connected to the closure element and engages the driving element. The coupling arm, in a first pivoted position thereof, is substantially rigidly connected to the driving element, and in a second pivoted position the closure element is fixed in position with respect to the vehicle the guide, whilst on the other hand the driving element is made movable with respect to the coupling arm and the closure element.Type: GrantFiled: April 3, 2002Date of Patent: November 25, 2003Assignee: Inalfa Roof Systems Group B.V.Inventors: Peter Christiaan Leonardus Johannes Manders, Egbert Boersma

Patent number: 6273500Abstract: A panel assembly for an open roof construction for a vehicle having an opening in its fixed roof comprises a panel of plastic material, a stiffening frame extending along the circumference of the panel assembly and connecting means for connecting said panel and said stiffening frame to each other. The stiffening frame is positioned substantially externally of the plastic panel. The connecting means consist of an encapsulation formed at least externally around said panel, which consists of a non-transparent material which is softer than the panel material and whose upper side is substantially flush with the upper side of the panel.Type: GrantFiled: August 3, 1999Date of Patent: August 14, 2001Assignee: Inalfa Industries B.V.Inventors: Egbert Boersma, Wilhelm Maria Theresia Hendricus Schrans

Patent number: 6257658Abstract: An open roof construction for a vehicle having an opening in its fixed roof comprises a panel for selectively closing or at least partially releasing the roof opening. An operating mechanism comprises a link formed of a metal plate or the like, which is connected to said closing element and which is fixed at the location of points of attachment. The link is provided with a slot for guiding a pin or the like, which slot is defined by plastic material on at least one side (upper side or underside), which plastic material is at least partially enclosed by metal plate on two sides (left side/right side). The link is formed of a single metal plate, at least at the location of said points of attachment. The plastic material of the link slot may consist of a rubbery base layer and of a sliding layer having a low coefficient of friction.Type: GrantFiled: August 27, 1998Date of Patent: July 10, 2001Assignee: Inalfa Industries B.V.Inventors: Martinus Wilhelmus Maria Nabuurs, Petrus Gerardus Marie Reivers, Egbert Boersma

Patent number: 6213544Abstract: An open roof construction for a vehicle having a roof opening in its fixed roof comprises a closing device for selectively closing or at least partially opening the roof opening. A driving element for the closing device comprises an outgoing driving wheel. At least one pull-push cable for providing the connection between the driving element and the closing device is guided in a cable guide and over the circumference of the driving wheel for adjustment of the cable by means of the driving element.

Patent number: 6102456Abstract: An apparatus is provided for manually moving closure an open roof construction for a vehicle between closed and opened positions. This apparatus includes an element which is removably connected to a securing element to be secured to a frame of the open roof construction and which is held in a connected position by a locking device. The locking device includes a locking member which is displaceable between locking and unlocking positions. The locking member is loaded to a locking position by a spring and displacement from the locking position to the unlocking position has the same direction as the releasing movement of the element with respect to the securing element.Type: GrantFiled: October 29, 1997Date of Patent: August 15, 2000Assignee: Inalfa Industries B.V.Inventor: Egbert Boersma
