Patent number: 11628770Abstract: Drive for an adjusting instrument, comprising a single motor, in particular an electric motor, and a driving shaft coupled therewith. The driving shaft cooperates via a transmission selectively with a first and a second driving path respectively. The drive comprises furthermore an operating mechanism with which the transmission is switchable between the first and the second driving path. The operating mechanism is energized by the motor via the driving shaft and is configured, upon successive energization of the motor from rest of the drive, to select alternately the first and the second driving path as initial driving path.Type: GrantFiled: March 21, 2019Date of Patent: April 18, 2023Assignee: MCi (Mirror Controls International) Netherlands B.V.Inventors: Paulus Gerardus Maria Van Stiphout, Bastiaan Bartjan Maat

Publication number: 20220348140Abstract: A drive component comprising a first rotation part and a second rotation part arranged to rotate together around a common central axis with respect to each other around that central axis. The drive component further comprises a rotation limiter operative between the two rotation parts, which limits rotation between them. The rotation limiter is so arranged that when the first rotation part is driven to rotation, the first rotation part after traversing a free angular stroke carries the second rotation part in a mutual angular position determined by the rotation limiter, i.e. the carry-along angle, along in rotation. The rotation limiter comprises an indexer energized by rotation of the first and/or second rotation part, so that in successive driving cycles on the drive component the carry-along angle is indexed and the rotation parts in successive driving cycles differ in mutual angular position at carry-along.Type: ApplicationFiled: September 23, 2020Publication date: November 3, 2022Applicant: MCi (Mirror Controls International) Netherlands B.V.Inventors: Anne Catharina Martha BEKKER, Bastiaan Bartjan MAAT, Tom Adriaan JANSEN, Alex LORIER, Paulus Gerardus Maria VAN STIPHOUT, Paul Michael WOLBER

Publication number: 20220185187Abstract: The invention relates to adjusting means for adjusting the position of a first part, in particular a viewing means holder part for a viewing means, such as a mirror or a camera for example, relative to a second part, in particular a base part, comprising at least one actuator, via which the first part can be moved, in particular pivoted, relative to the second part. The actuator has at least one first toothed ring segment and at least one second toothed ring segment, wherein the first toothed ring segment is force-coupled to at least one first actuator—in particular, a position detector—and the second toothed ring segment is force-coupled to at least one second actuator—in particular, an actuating drive. The invention additionally relates to a view adjusting means comprising such an adjusting means.Type: ApplicationFiled: March 19, 2020Publication date: June 16, 2022Applicant: MCi (Mirror Controls International) Netherlands B.V.Inventors: François Roderik Henri BOUAZIZ, Paulus Gerardus Maria VAN STIPHOUT, Stefan Fritz BROUWER, Bastiaan Bartjan MAAT, Anne Catharina Martha BEKKER, Tom Adriaan JANSEN, Alex LORIER

Patent number: 11247612Abstract: The invention relates to an adjusting instrument for an exterior mirror unit of a vehicle, including a support unit and a housing unit pivotable in a circumferential direction between a plurality of positions relative to the support unit. Furthermore, the adjusting instrument includes a breakable rotation-locked coupling unit for coupling of the housing unit to the support unit. The coupling unit comprises a plural number N of parallel disposed couplings where each coupling has two mutually opposed coupling faces, pressed against each other under spring action and mutually displaceable in the circumferential direction. The coupling faces have a periodic cam pattern engaging in each other, wherein the two coupling faces are mutually breakably rotation-locked and wherein only a limited number M of couplings is in engagement at the same time, with M being less than N.Type: GrantFiled: May 3, 2018Date of Patent: February 15, 2022Assignee: MCi (Mirror Controls International) Netherlands B.V.Inventors: Bastiaan Bartjan Maat, Paulus Gerardus Maria Van Stiphout, François Roderik Henri Bouaziz

Wearable support structure for at least partly relieving a human body during leaning or bending over
Patent number: 10588771Abstract: Wearable support structure assists in at least partly relieving a human body during leaning or bending over includes a frame. The frame has a chest support for bearing upon a chest of the human body, pivoting arrangements for pivoting the support structure in correspondence with the leaning or bending or the human body, and two elongated stays connected to the chest support. The stays extend substantially alongside opposite sides of the human body and connect to the pivoting arrangements. stays are resilient stays arranged such that they are in a stretched state corresponding with an upright position of the human body when being unloaded, and arranged to be biased back to the stretched state when being bent into a bent state corresponding with a leaning or bending position of the human body. The structure further includes a lumbar support and a thigh support.Type: GrantFiled: March 10, 2016Date of Patent: March 17, 2020Assignee: Laevo B.V.Inventors: Michael Martinus Holscher, Bastiaan Bartjan Maat, Robert Huitema, Boudewijn Martin Wisse -
