Title: Airbag protection for vehicle occupants - has progressive action to position occupant before full airbag pressure is applied
Inventor: SINNHUBER RUPRECHT DIPL ING
IPC: B60R21/26
Filed: 1993-06-17
Abstract: The airbag system is activated by collision sensors. The protection is enhanced by ensuring that the occupant is correctly positioned in the seat before the full airbag (4) pressure is released. This is achieved by a progressive action airbag, or by additional position control airbags or by movable padded sections of the seat. The collision sensor action is extended to include a more sensitive, longer reach mode, to pre-empt the main sensor action. This can include microwave proximity sensors which can be used to predict a collision. The position control airbag action can be powered by a separate pressure source powered from a reservoir and pumped by the engine. ADVANTAGE - Occupant is correctly positioned for maximum protection from airbag, less injury risk.

Patent DE-4322769-A1 (DE)
Title: Drive-type closure
IPC: E04B1/61
Filed: 1993-07-08
Abstract: The invention proposes a drive-type closure in one and two parts having drive parts offset by 180 DEG , the closure being actuated in rotation on a pin and comprising two interconnected shells which are angled off with respect to one another through 90 DEG  at the outer-border projections in order to form tracks. Open over the functional region, the track pairs lead elliptically inwards in the form of a screw and slightly outwards in the inclusion region. Running outwardly, the track pairs, projecting, form an introduction opening such as projecting claw pairs for receiving one or two opposite counter-bolts. T-shaped ends of connecting rods. Upon actuation by rotating in the closure direction, the counter-bolts (T-shaped ends) are drawn via the tracks into the drive-type closure. In the enclosure region of the track pairs leading outwards slightly out of a circular path, locking against independent release is achieved. In the closed state, draws in the closure direction. Acts kinematically. The drive-type closure in one and two parts can preferably be used for connecting components which can be separated from one another again at any time.

Patent DE-4338073-A1 (DE)
Inventor: BRAUN FRITZ
IPC: F16H63/42
Filed: 1993-11-08
Abstract: 1.2. Various methods and devices of this type are known, for example those which generate only shift-recommendation signals or those which, when predeterminable threshold values are exceeded during driving, emit a warning signal when an unfavourable driving mode lasts too long and which record the number of warning signals given. 2.2. In the new method, a first evaluation number relating to the traction mode of the motor vehicle is formed, a second evaluation number relating to the driving mode free of engine load is formed, a third evaluation number relating to the deceleration mode of the motor vehicle is formed and, by weighted averaging from the three individual evaluation numbers, a total evaluation number is formed. This allows the differentiated objective evaluation of the driver-influenceable driving behaviour. 2.3. The invention is used, for example, in commercial vehicles. <IMAGE>
