  Description

  Chair for enhancing comfort when required to be seated for long durations, such as in aeroplane, auditorium, theater, waiting lounge, automobile, library and the like. When for use in a public seating arrangement having multiple chairs laid one behind the other, a foot rest (210) is provided on the chair, at a height H from the floor level (220), the foot rest (210) on a first chair (100a) being usable by a person seated on a second chair (100b) that is behind the first chair (100a). In another aspect, the foot rest (210) is provided at a front side (290) of the chair at a height H that is closer to a seat level (280) than to the floor level (220), for use by a person seated on the same chair, while having to lift the knee joints significantly above the seat level (280). The foot rest (210) is preferably sling type

• device for tensioning safety belts
  Preview

  Description

  The invention relates to a device for tensioning safety belts, comprising a housing, a pyrotechnic propellant charge (3), which is placed inside the housing (1) and which acts upon a piston (5) mounted inside the housing (1) an a manner that enables it to be displaced. An especially compact and versatilely applicable design can be achieved by virtue of the fact that the piston (5) is actively connected to a pull strip (13) that is wound onto a drive wheel (11), which is connected to an actuating shaft (16) designed for exerting a torque onto a winding device, which is coupled to the device and which is provided for winding the safety belt.

  L'invention concerne un dispositif permettant de tendre des ceintures de sécurité, comprenant un boîtier, une charge propulsive (3) pyrotechnique disposée dans le boîtier (1), qui agit sur un piston (5) monté mobile dans le boîtier (1). L'invention permet de parvenir à une conception particulièrement compacte et permettant des utilisations multiples, du fait que le piston (5) coopère avec une bande de traction (13), qui est enroulée sur un disque d'entraînement (11), relié à un arbre d'actionnement (16), conçu de manière à exercer un couple sur un dispositif d'enroulement accouplé audit dispositif, pour la ceinture de sécurité.

  Description

  The invention relates to the use of mineral fibres or filaments and E- glass fibres having a SiO2 part of more than 50 wt. % in the form of a textile fabric, as a biocide-free antifouling agent for protecting submerged structures from damage by adhesion and multiplication of aquatic pests in the sea or in industrial water systems. The surface of the antifouling agent predominantly consists of fine basalt fibres and the fabric is woven, knitted or braided, a fabric formed according to multiaxial technology, or a nonwoven.

• MOVABLE BALLAST WEIGHT FOR SAILING SHIPS
  Preview

  Description

  Conventional sailing ships have a keel with a ballast weight which counteracts the listing of the ship. The disadvantage thereof is that the righting torque of the keel weight occurs only after a specific tilt of the ship, which in turn means a loss of efficiency of the sail and thus a loss of speed. Furthermore, the conventional keel weight must have a very large mass since the weight force thereof under water is significantly reduced because of buoyancy. The novel flexible ballast weight according to the invention solves this problem by mounting said ballast weight on both side walls above the waterline and by shifting said ballast weight to the windward side of the ship via a connecting brace by means of a gear drive. This design allows a significantly lower mass of the flexible ballast weight compared to the conventional keel weight because of the greater weight above water, which in turn means a total displacement of the ship, and thus higher speed. In addition, the listing forces of the ship can be more quickly equalized by early shifting of the ballast weight onto the windward side compared to conventional keel ships, which makes possible a more upright sailing and thus a higher speed.
