11. 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 the airbag is deployed in the activated and filled condition between a front vehicle seat and an upper body region of the passenger and 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 igniting a pyrotechnic propellant upon activation to release the gas filling the airbag, wherein the airbag has a support structure that is fillable with the gas at least in a first region assigned to the upper body region of the passenger so that support structure bearing structures encasing at least one bearing volume are stretched, wherein the airbag has a second region adjacent to the first region and assigned to the knee and lower leg region of the passenger, the second region is a single chamber-like 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 (12, 13, 14, 15, 16, 17)

18. A vehicle, comprising:
-
a front vehicle seat; a rear vehicle seat upon which at least one passenger is positioned; and an airbag assigned to 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 the airbag is deployed in the activated and filled condition between a front vehicle seat and an upper body region of the passenger and 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 igniting a pyrotechnic propellant upon activation to release the gas filling the airbag, wherein the airbag has a support structure that is fillable with the gas at least in a first region assigned to the upper body region of the passenger so that support structure bearing structures encasing at least one bearing volume are stretched, wherein the airbag has a second region adjacent to the first region and assigned to the knee and lower leg region of the passenger, the second region is a single chamber-like 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 (19, 20, 21, 22, 23, 24)

25. 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 igniting a pyrotechnic propellant of 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 arranged between a front vehicle seat and an upper body region of the passenger and 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 assigned to the upper body 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 and, is arranged in the knee and lower leg region of the passenger, the second region is a single chamber-like 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 (26, 27)
