Abstract

A motor vehicle, encompassing a body, a drive motor, in particular an internal combustion engine and/or an electric motor, a crash detection device, a computing unit, at least one front seat with a seat part and a back part, at least one rear seat with a seat part and a back part, at least one rearward displacement device for the at least partial rearward displacement of the at least one front seat during a pre-crash phase acquired by the crash detection device, wherein the seat part of the at least one rear seat has built into it a first means for lifting up the legs of an individual on the at least one rear seat during the pre-crash phase, and the back part of the at least one front seat has built into it a second means for the rearward movement of the legs of the individual on the at least one rear seat during the pre-crash phase.

Claims

1. A motor vehicle, comprising:

a body;

a drive motor, comprising at least one of an internal combustion engine and an electric motor;

a crash detection device;

a computing unit;

at least one front seat with a seat part and a back part;

at least one rear seat with a seat part and a back part; and

at least one rearward displacement device for at least partial rearward displacement of the at least one front seat during a pre-crash phase acquired by the crash detection device,

wherein the seat part of the at least one rear seat has a first inflatable member for lifting up legs of an individual on the at least one rear seat during the pre-crash phase, and the back part of the at least one front seat has a second inflatable member for pushing the legs of the individual rearward during the pre-crash phase.

2. The motor vehicle according to claim 1, wherein the computing unit is configured to initially activate the first inflatable member, and subsequently the second inflatable member.

3. The motor vehicle according to claim 1, wherein the computing unit is configured to initially activate the first inflatable member and/or the second inflatable member, and wherein the at least one rearward displacement device is configured to subsequently and/or simultaneously be activated.

4. The motor vehicle according to claim 1, wherein a sensor system is configured to acquire the position of the legs of the individual on the at least one rear seat, and, depending on the acquired position of the legs, the rearward displacement of the at least one front seat is performed with the at least one rearward displacement device.

5. The motor vehicle according to claim 1, wherein the computing unit is configured to calculate an available rearward displacement path for the at least one front seat as a function of the acquired position of the legs, and an actual rearward displacement path of the at least one front seat is at the most available rearward displacement path.

6. The motor vehicle according to claim 1, wherein an occupancy sensor is configured to acquire an occupancy of the at least one rear seat by the individual, and when the individual is on the at least one rear seat, the first inflatable member and the second inflatable member assigned to the occupied rear seat only are activated.

7. The motor vehicle according to claim 1, wherein the first inflatable member is a first airbag, and

the second inflatable member is a second airbag.

8. The motor vehicle according to claim 1, wherein the motor vehicle encompasses two front seats, wherein the back part of each of the two front seats has a respective second inflatable member, and the motor vehicle encompasses two rear seats, wherein each of the two rear seats is situated behind a respective one of the two front seats and has a respective first inflatable member.
