Abstract

The invention relates to a seatbelt device (S) for a vehicle (F), comprising a webbing (3) with a belt buckle tongue (4) displaceably arranged thereon, which can be inserted into a buckle (5) as a belt anchoring point (G1) Gurtendbeschlag (6) and a belt retractor (7) each form a further Gurtanankerungspunkt (G2, G3). According to the invention, at least one belt anchoring point (G1 to G3) is displaceably mounted in the direction of a vehicle longitudinal axis (x) as a result of the situation and / or forces.

Description

The invention relates to a seatbelt device for a vehicle, comprising a webbing with a belt buckle tongue displaceably arranged thereon, which can be inserted into a buckle as a belt anchor point, wherein a Gurtendbeschlag and a belt retractor each form a further Gurtanankerungspunkt.

In general, a three-point belt is known as a seat belt device in a vehicle. The seatbelt apparatus comprises a webbing having a buckle tongue slidably disposed thereon and insertable into a buckle associated with the webbing such that an occupant carrying the webbing is tethered to the vehicle via three webbing anchorage points. The buckle, an end fitting and a belt retractor each form a Gurtanankerungspunkt.

The invention has for its object to provide a comparison with the prior art improved safety belt device.

The object is achieved by the features specified in claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

A seatbelt apparatus for a vehicle includes a webbing having a buckle tongue slidably disposed thereon and insertable into a buckle as a webbing anchoring point, a webbing fitting and a webbing retractor each forming another webbing anchoring point. According to the invention, at least one belt anchoring point is displaceably mounted in the direction of a vehicle longitudinal axis as a function of the situation and / or forces.

Due to the displaceable mounting of the at least one Gurtverankerungspunktes slipping under a lap belt portion of the seat belt, the so-called submarining effect, largely counteracted.

In this case, the safety belt device is a comparatively robust device, at least for reducing the submarining effect, wherein a retention of a pelvic area of an occupant carrying the webbing and an optimum position of the webbing in relation to the pelvic area are optimally attuned. Thereby, a risk of injury to the occupant by the webbing in the event of a collision of the vehicle, especially in a frontal collision, significantly reduced.

Embodiments of the invention will be explained in more detail below with reference to a drawing.

• 1 schematisch einen Ausschnitt eines Fahrzeuges mit einem Insassen auf einem Fahrzeugsitz.

It shows:

• 1 schematically a section of a vehicle with an occupant on a vehicle seat.

In the single figure is a section of a vehicle F with an inmate 1 on a vehicle seat 2 shown, the inmate 1 a the vehicle seat 2 assigned webbing 3 a seat belt device S has created.

The seat belt device S is designed as a three-point belt and includes the webbing 3 with a belt buckle displaceably arranged thereon 4 which is in a buckle 5 is pluggable.

In addition, the seat belt device S a belt end fitting 6 and a belt retractor 7 on, with the Gurtendbeschlag 6 , the belt retractor 7 and / or the buckle 5 a belt tensioner and / or a belt force limiting unit comprises or comprises.

The buckle 5 , the belt end fitting 6 and the belt retractor 7 each form a Gurtanankerungspunkt G1 to G3 where the inmate 1 when wearing webbing 3 about these three belt anchorage points G1 to G3 to the vehicle F is connected.

This forms the buckle 5 a belt anchor point G1 , the belt end fitting 6 a first further belt anchor point G2 and the belt retractor 7 a second further belt anchoring point G3 ,

That's the belt anchor point G1 forming buckle 5 is in the present embodiment on the vehicle seat 2 arranged.

In the created state is the webbing 3 in a lap belt section 3.1 and a shoulder belt portion 3.2 divided.

In case of collision of the vehicle F especially in a frontal collision, and the danger of the occupant 1 , in particular its pelvis, by acting acceleration under the lap belt section 3.1 slips through, is provided, at least one of the belt anchoring points G1 to G3 in the direction of the vehicle's longitudinal axis x slidably store. Slipping under the lap belt section 3.1 is also known as the so-called submarining effect.

In the present embodiment, the buckle 5 as a belt anchor point G1 in the direction of the vehicle's longitudinal axis x slidably mounted by a predetermined amount, allowing the best possible coordination between a restraint of the occupant's pelvis 1 and an optimal webbing position, in particular the lap belt section 3.1 , is realized.

For example, for displaceable mounting one in the direction of the vehicle longitudinal axis x extending guide rail 8th at the vehicle seat 2 and / or arranged on another suitable vehicle part.

In case of collision and imminent danger of submarining effect, the belt anchor point shifts G1 due to the slidable storage situational and forces conditional in the direction of the vehicle longitudinal axis x , leaving a space between the webbing 3 , in particular the lap belt section 3.1 , and the occupant's pelvis 1 is reduced.

By reducing the distance between the pelvis and the webbing 3 the risk of pelvic rotation and the risk of submarining is significantly reduced, with the movement of the seatbelt anchorage point G1 as a function of a collision process and as a function of a collision acceleration-related advancement of the occupant 1 can be done. The retention of the pelvis of the occupant 1 by means of the lap belt section 3.1 of the webbing 3 So it is adapted to the situation and strength.

Alternatively or in addition to that, the buckle 5 as a belt anchor point G1 slidably mounted, can also Gurtendbeschlag 6 as the first further belt anchoring point G2 and / or the belt retractor 7 as the second further belt anchoring point G3 in the direction of the vehicle's longitudinal axis x be arranged slidably.
