Abstract
A knee protection device (1) for a person (2) sitting on a seat arranged inside a motor vehicle is provided in the case of an accident-related deformation of the leg space. The device has a load distribution plate (3) which is driven instantaneously from its rest position in the direction toward the knee parts of the person (2), upon activation of the trigger device attached to it. The trigger device may be a pyrotechnic device (4) of the type used for a safety belt attached to the seat.
Claims9
A knee protection device (1) for a person (2) sitting on a seat arranged in a motor vehicle interior for inhibiting forward movement of the knees of a person (2) during an accident, the knee protection device (1) comprising:
- a load distribution plate (3) having a first side which is adapted to face the person and a second side which is adapted to face away from the person, the load distribution plate being held and guided by guide rods (5, 6) comprising at least partially energy-absorbing deformation elements (7, 8) operatively associated with the second side of the load distribution plate (3), said trigger device (4) instantaneously driving the load distribution plate from a rest position in a direction toward the knees of the person (2) upon activation of the trigger device, wherein the trigger device comprises a pyrotechnic. device (4).
A knee protection device (1) for a person (2) sitting on a seat arranged in a motor vehicle interior for inhibiting forward movement of the knees of a person during an accident, the motor vehicle having a cross support adjacent the leg space, the knee protection device (1) comprising:
- a load distribution plate (3);
- guide rods (5, 6) adapted for sliding connection to the cross support, one end of each guide rod being connected to the load distribution plate (3) to thereby guide movement of the load distribution plate, a deformation element (7, 8) that is at least partially energy-absorbing operatively connected between the load distribution plate and each guide rod;
- and trigger device (4) being operatively connected to the load distribution plate (3), said trigger device (4) instantaneously driving the load distribution plate under guided movement from said guide rods with respect to the cross support from a rest position in a direction toward a knee of the person (2) upon activation of the trigger device (4).
