Description

453 211 Den på ritningen visade dörren 1 till ett motorfor- don 2 har âtergivits i två olika lägen, nämligen dels med streckade linjer i ett nära intill det stängda läget lig- gande läge och dels med heldragna linjer i det stängda läget. För att överföra dörren 1 från det första till det andra läget tjänar en servomanövrerad stängningsan- ordning som skall beskrivas närmare i det följande. 453 211 The door 1 to a motor vehicle 2 shown in the drawing has been reproduced in two different positions, namely partly with dashed lines in a position close to the closed position and partly with solid lines in the closed position. To transfer the door 1 from the first to the second position, a servo-operated closing device serves, which will be described in more detail in the following.

Vid dörren 1 är fäst en till fordonets elektriska system ansluten elektrisk strömställare 3, vars manöver- stång 3a vid förande av dörren 1 till det med streckade linjer visade läget kommer till anliggning mot en med for- donet fast förbunden konstruktionsdel 4. Härigenom påverkas strömställaren 3 och via en icke visad ledningsanslutning igångsättes en i fordonet fast monterad elektrisk motor 5, som tjänar till drivning av ett kring en axel 6 svängbart stängningsfinger 7. Detta finger 7, som är svängbart 3600 samverkar formbundet, såsom framgår av fig 2 på ritningen, endast inom ett begränsat svängningsvinkelområde med en vid dörren 1 anordnad fast medbringarkloss 8 för att över- föra dörren 1 till det med heldragna linjer visade stängda läget. Svängningen av stängningsfingret 7 sker i riktningen för pilen 9.Attached to the door 1 is an electric switch 3 connected to the vehicle's electrical system, the control rod 3a of which, when leading the door 1 to the position shown in broken lines, comes into abutment against a structural part 4 connected to the vehicle. and via a line connection (not shown) an electric motor 5 mounted in the vehicle is started, which serves to drive a closing finger 7 pivotable about a shaft 6. This finger 7, which is pivotable 3600, cooperates in a form-fitting manner, as shown in Fig. 2 of the drawing, only within a limited angle of rotation with a fixed carrier block 8 arranged at the door 1 for transferring the door 1 to the closed position shown in solid lines. The closing finger 7 pivots in the direction of the arrow 9.

I fig 2 pâ ritningen har stängningsfingret 7 visats med heldragna linjer i sitt ugângsläge, med streckade lin- jer i början av dess samverkansområde med medbringarklossen 8 och med punktstreckade linjer vid slutet av detta sam- verkansområde.In Fig. 2 of the drawing, the closing finger 7 has been shown with solid lines in its initial position, with dashed lines at the beginning of its co-operation area with the carrier block 8 and with dotted lines at the end of this co-operation area.

Regleringen av den elektriska motorn S kan därvid ske på sådant sätt att motorn via strömställaren 3 endast igångsättes vid stängning, dvs, anpressning, av dörren 1, varefter stängningsfingret 7 vrids 3600. Man skulle emel- lertid också kunna tänka sig att den elektriska motorn igångsättes vid såväl öppnandet som stängandet av dörren 1 och därmed åstadkommer en svängningsrörelse av stängnings- fingret 7 av 1800. °The control of the electric motor S can then take place in such a way that the motor via the switch 3 is only started when closing, ie, pressing, of the door 1, after which the closing finger 7 is turned 3600. However, it would also be conceivable for the electric motor to be started. at both the opening and the closing of the door 1 and thus produces a pivoting movement of the closing finger 7 of 1800 °.

Claims

The solution proposed according to the invention thus provides a simple possibility of achieving a comfortable and quiet closing of vehicle doors, whereby only a slight pressing of the door to a position close to the closed position is required manually. P a t e n t k r a v

Auxiliary force-actuated device for closing doors, doors and the like, in particular in the case of motor vehicles, which at a position of the door or equivalent close to the closing position can be activated via a switch and have a form-cooperating interaction and at the door or equivalent and an adjacent, actuating elements arranged with the vehicle fixedly connected to the vehicle, one of which is designed stationary and a movable such as a closing finger (7) which can be pivoted by means of an auxiliary drive device, characterized in that the closing finger (7) is pivotable 3600 in only one direction and thus cooperating stationary actuating element is designed as a carrier block (8), and that the cooperating outer contours of the two actuating elements are designed such that entraining takes place only over a limited pivot angle range of the closing finger (7).

An annex ax according to claim 1, characterized in that an electric motor (5) is provided for driving the closing eye (7), which during each actuation by means of the switch (3) which takes place only when the door is closed. (1) or equivalent, causes a pivoting of the closing finger (7) 3600.

Device according to Claim 1, characterized in that an electric motor (5) is provided for driving the closing finger (7), which, when both opening and closing the door (1) or the like, is activated by means of the switch (3) and thereby provides a oscillation of the closing finger (7) 1800.

Device according to claim 1, characterized in that the closing finger is designed with two arms and when closing the door an angle of 180 ° is pivoted stepwise.
