Abstract: A hydraulic vibration-damping support comprising two strength members interconnected by an elastomer body which defines a working chamber communicating with a compensation chamber via a constricted passage. The two hydraulic chambers are separated from each other by a rigid partition formed by two gratings disposed one on the other, and a decoupling flap is mounted with a small amount of clearance between the gratings. The decoupling flap is provided with two catches that are clipped onto one of the gratings.

Abstract: The motor vehicle seat comprises a seat proper and a seat back. The seat is caused to go from a passenger position to a first load position by causing the seat proper to pivot through 90° about a horizontal axis close to its front edge, and by causing the seat back to pivot through 90° about a horizontal axis close to its bottom edge. The seat back thus comes to occupy the space that is occupied by the seat proper when it is in the passenger position. The seat is caused to go from the first load position to a second load position by causing the seat proper to pivot through a further 90° about its horizontal axis. The seat is caused to go from the passenger position to the first load position, and then from the first load position to the second load position, by actuating a single handle.

Abstract: An extrusion apparatus includes first and second die body portions each having a main body and a lip interconnected with the main body wherein the die body portions are joined such that a die outlet is formed between the lips. The apparatus also includes at least one pivoting link coupled to one of the lips and a sliding member coupled to the pivoting link whereby movement of the sliding member causes the pivoting link to pivot and move the one lip relative to the other lip.

Abstract: A flexible cover for a vehicle seat has an inside face with a conductive thread fixed thereagainst to form a seam in chain stitch that does not pass through the cover and that is not visible on the outside face of the cover.

Abstract: System for a vehicle that has a seat fitted with a measuring device of the electromagnetic field type, an airbag arranged to protect the occupant of the seat in the event of an accident, this airbag having several modes of operation, and an operating device designed to cause the airbag to inflate in the event of an accident, selectively according to one of the modes of operation of this airbag on the basis of a parameter representing the mass of the occupant of the seat, as measured by the electromagnetic field-type measuring device.

Abstract: Vehicle seat underframe comprising a framework provided with a lower guide shoe and with a moving catch comprising a lateral claw that can move between a locked position and a retracted position. The device for operating the catch is connected to a release cam which normally holds a release finger in the effaced position. When the catch is in the retracted position, the release finger moves into an active position in which a lower end of this finger projects downwards with respect to the framework while an upper end of the release finger immobilizes the release cam.

Abstract: A feedblock for supplying a multi-layer stream of polymeric material to an extrusion die is provided wherein the dimension of at least some of the layers of the multi-layer stream can be precisely adjusted and/or controlled. The feedblock includes a primary flow path which is used to create a first layer and two secondary flow paths which are used to create a set of second and third layers. The secondary flow paths are positioned relative to the primary flow path such that the second and third layers are deposited on opposing sides of the primary layer in a sandwich-like configuration. Each of the secondary flow paths include a contoured slot through which a secondary fluid stream of polymeric material is deposited onto a primary stream of polymeric fluid flowing in the primary flow path. The contoured slot is geometrically shaped such that adjusting the position of the contoured slot alters the shape of the secondary fluid stream as it is deposited onto the primary flow path.

Abstract: A seat has a back connected to a seat proper via a hinge comprising two cheekplates that can be secured to each other by means of toothed slugs controlled by a cam. In order to enable the seat back to be folded down forwards, and then to return the back into its initial position, the cam of the hinge is associated with an external memory mechanism implemented in the form of a self-contained assembly which includes its own drive member connected to the cam by a mechanical connection including lost motion that is adapted so that actuation of the cam does not move the drive member, and so that actuation of the drive member causes the cam to be moved towards its unlocked position.

Abstract: This invention is a system that tracks the 3-dimensional position and orientation of one or more bodies (20) in a volume by a light based as well as at least one non-light based mensuration sub-system. This overcomes the limitation of light based mensuration systems to the necessity of the bodies (20) to be in constant line-of-sight of its light based position sensors (26). The invention possesses most of the accuracy and stability of its light based position measurement sub-system (24, 26, 72), but can also work without direct line of sight either for short periods of time or within certain parts of the volume. It does so by incorporating other sensors (31, 34), such as inertial or magnetic, which are frequently recalibrated against the light based sub-system (24, 26, 72) while the bodies (20) are visible by the light based sub-system (24, 26, 72).

Abstract: Disclosed is a wireless instrument tracking system. The wireless instrument tracking system is used for determining the location of at least one point relative to the instrument in a three-dimensional space relative to a three-dimensional coordinate tracking system. Advantageously, a first wireless instrument can be placed into the optical field with the wireless instrument including a wireless receiver and at least one optical position indicator. The optical position indicator is typically light emitting diodes (18) and communicates with corresponding measurement sensors (30) across a wireless optical link. The wireless optical link is time multiplexed with repetitive time frames divided into time slots. Each LED (18) emits an infrared signal or flashes in a respective time slot of a time frame. The measurement sensors (30) are preferably CCD cameras.

Abstract: A vehicle seat back comprises firstly a rigid frame having first and second side uprights and top and bottom cross-members interconnecting the first and second side uprights, and secondly a resilient supporting sheet fixed to the rigid frame and placed so as to come directly into contact with the back of a user. The supporting sheet forms a bag that is fitted onto the rigid frame over its first side upright so as to cover the top and bottom cross-members and the first side upright, the resilient supporting sheet being fixed to the second side upright.

Abstract: A device for detecting or following the position of a bone is described. The device comprises a holder (10) for a position indicator, and a gripping mechanism (20, 30) for fastening the holder (10) to the bone. The gripping mechanism (20, 30) is designed to surround the bone on two opposite sides and on a further, third side and executes a constrained movement in the direction of the third side as the bone is being surrounded by the gripping mechanism (20, 30) on the two opposite sides.

Abstract: A compression dressing for the treatment of lymphoedema can be applied directly by a patient without requiring the assistance of trained nursing staff. The dressing comprises a panel (1) of elastically stretchable material the outer surface of which has a loop pile structure. The panel is sized so that it can wrap once around a patient's limb with some overlap. A separable slide fastener is provided for connecting the panel to itself into a tubular support around the patient's limb, and comprises two rows of inter-engageable teeth mounted on two separate tapes (5,8). One tape (5) is secured to one longitudinal edge of the panel (1) and the other tape (8) is secured to an anchorage element which comprises a number of mutually spaced fabric tabs (11) each having on an under-surface hooks for anchoring the anchorage element (11) to the loop pile structure of the panel (1). The invention also provides a method of applying such a dressing to the limb of a patient.
