1. A passenger protection device for a vehicle, the passenger protection device comprising:
- an airbag assigned to at least one passenger in a rear compartment of the vehicle,wherein, in event of an imminent collision of the vehicle being detected or in the event of a collision, the airbag is activated and filled with a gas,wherein the airbag has a form such that when the airbag is deployed in the activated and filled condition, the airbag is configured to be interposed between a front vehicle seat and a lower torso and pelvic region of the passenger and configured to be interposed between the front vehicle seat and a knee and lower leg region of the passenger,wherein the airbag is fluidically connected to a gas generator for deployment of the airbag, the gas generator, upon activation, releases the gas filling the airbag,wherein the airbag has a support structure that is fillable with the gas at least in a first region configured to press the pelvic region of the passenger towards a rear of the vehicle and to protect the lower torso and pelvic region of the passenger so that support structure bearing structures, which encase at least one bearing volume, are stretched by sucking in surrounding air through at least one inflow opening into an interior of the first region and forming the at least one bearing volume,wherein the airbag has a second region adjacent to the first region and configured to protect the knee and lower leg region of the passenger, the second region is a single fillable region,wherein the second region is fluidically connected to the support structure of the first region, andwherein the support structure is tubular.

8. A vehicle, comprising:
-
a front vehicle seat; a rear vehicle seat upon which at least one passenger is positioned; and an airbag configured to protect the at least one passenger, wherein, in event of an imminent collision of the vehicle being detected or in the event of a collision, the airbag is activated and filled with a gas, wherein the airbag has a form such that when the airbag is deployed in the activated and filled condition, the airbag is configured to be interposed between a front vehicle seat and a lower torso and pelvic region of the passenger and configured to be interposed between the front vehicle seat and a knee and lower leg region of the passenger, wherein the airbag is fluidically connected to a gas generator for deployment of the airbag, the gas generator, upon activation, releases the gas filling the airbag, wherein the airbag has a support structure that is fillable with the gas at least in a first region configured to press the pelvic region of the passenger towards a rear of the vehicle and to protect the lower torso and pelvic region of the passenger so that support structure bearing structures, which encase at least one bearing volume, are stretched by sucking in surrounding air through at least one inflow opening into an interior of the first region and forming the at least one bearing volume, wherein the airbag has a second region adjacent to the first region and configured to protect the knee and lower leg region of the passenger, the second region is a single fillable region, wherein the second region is fluidically connected to the support structure of the first region, and wherein the support structure is tubular. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of deploying an airbag assigned to at least one passenger in a rear compartment of the vehicle, the method comprising:
-
activating and filling the airbag with gas by a gas generator fluidically connected to the airbag in response to detection of an imminent collision of the vehicle or in response to detection of a collision; wherein filling the airbag causes the airbag to move from a stored position to a deployed position in which the airbag is configured to be interposed between a front vehicle seat and a lower torso and pelvic region of the passenger and configured to be interposed between the front vehicle seat and a knee and lower leg region of the passenger, wherein in the deployed position a support structure of the airbag is filled with the gas at least in a first region configured to protect the lower torso and pelvic region of the passenger so that support structure bearing structures encasing at least one bearing volume are stretched, wherein in the deployed position a second region of the airbag, which is adjacent to the first region, is configured to press the pelvic region of the passenger towards a rear of the vehicle and to protect the knee and lower leg region of the passenger, wherein the second region is a single fillable region, wherein the second region is fluidically connected to the support structure of the first region, wherein the support structure is tubular, and wherein the airbag is only activated when a current driving speed of the vehicle is below a predetermined threshold value. - View Dependent Claims (16, 17)
