Abstract
The present invention discloses an anti-submarine seat for an automobile. The anti-submarine seat prevents the occupant pelvis from slipping forward during a collision. The present invention discloses installing spring-type actuator means at a lower portion of a seat cushion so as to raise a front end of the seat cushion and to descend the rear end of the seat cushion at the time of an impact.
Claims9
An anti-submarine seat for an automobile, comprising spring-type actuators elastically supporting a front end and a rear end of a seat cushion of an automobile, the actuators being installed at a lower portion of the seat cushion, wherein the actuators urge the front end of the seat cushion upwards and simultaneously descend the rear end of the seat cushion in response to an impact due to a collision and wherein the actuators comprise;
- a cylindrical upper housing installed at a lower surface of an upper seat frame of the seat cushion;
- a cylindrical lower housing installed at an upper surface of the lower seat frame of a floor of an automobile;
- and
- a spring and a spring seat installed in the lower or upper housing, wherein the spring and the spring seat are fixed in the lower or upper housing by means of a wedge-shaped spring fixing pin in the actuator so that an operation of the spring is selectively controlled.
An anti-submarine seat for an automobile, comprising spring-type actuators elastically supporting a front end and a rear end of a seat cushion of an automobile, the actuators being installed at a lower portion of the seat cushion, wherein the actuators urge the front end of the seat cushion upwards and simultaneously descend the rear end of the seat cushion in response to an impact due to a collision and wherein a spring is installed in a lower housing of the actuators installed at the front end of the seat cushion, and the spring is installed in an upper housing of the actuators installed at the rear end of the seat cushion.
An anti-submarine seat for an automobile, comprising spring-type actuators elastically supporting a front end and a rear end of a seat cushion of an automobile, the actuators being installed at a lower portion of the seat cushion, wherein the actuators urge the front end of the seat cushion upwards and simultaneously descend the rear end of the seat cushion in response to an impact due to a collision and wherein the actuators are activated by applying a force to a seat belt.
A anti-submarine seat for an automobile, comprising:
- a vehicle seat configured with a front lower seat portion and a rear lower seat portion wherein said front lower seat portion is positioned moveably adjacent to said rear lower seat portion;
- a plurality of first actuators coupled between a frame of said first lower seat portion and the floor of the automobile and configured to translate said first lower seat portion upward following activation;
- and
- a plurality of second actuators coupled between a frame of said rear lower seat portion and the floor of the automobile and configured to translate said rear lower seat portion downward following activation.
