Apparatus for Knee Airbag

Abstract

An embodiment apparatus for a knee airbag includes an airbag located inside a cockpit, the cockpit configured to be located in a front side of an interior of a vehicle, an airbag door disposed in the cockpit at a position facing an occupant knee area, the airbag door being configured to open when the airbag is deployed, an absorber located at a front end of the airbag, and a guide part surrounding at least two surfaces of the absorber and the airbag.

What is claimed is: 
     
         1 . An apparatus for a knee airbag, the apparatus comprising:
 an airbag located inside a cockpit to be located in a front side of an interior of a vehicle;   an airbag door disposed in the cockpit at a position facing an occupant knee area, the airbag door being configured to open when the airbag is deployed;   an absorber located at a front end of the airbag; and   a guide part surrounding at least two surfaces of the absorber and the airbag.   
     
     
         2 . The apparatus of  claim 1 , wherein the guide part surrounds a front surface of the absorber and upper and lower surfaces of the absorber and the airbag. 
     
     
         3 . The apparatus of  claim 1 , wherein the guide part surrounds a front surface of the absorber and left and right surfaces of the absorber and the airbag. 
     
     
         4 . The apparatus of  claim 1 , wherein the absorber comprises two foams located adjacent to each other when the airbag is in a non-deployed state. 
     
     
         5 . The apparatus of  claim 4 , wherein the two foams are configured to be spaced apart from each other along a front surface of the guide part when the airbag is in a deployed state. 
     
     
         6 . The apparatus of  claim 5 , wherein the airbag extends between the two foams spaced apart from each other. 
     
     
         7 . The apparatus of  claim 1 , wherein the airbag is mounted in a folded state in a same direction as an outer surface of the cockpit, and wherein the guide part is located on sides of the airbag in a folded state in a direction perpendicular to the outer surface of the cockpit. 
     
     
         8 . The apparatus of  claim 7 , wherein, when the cockpit has an angle that is greater than a first reference value based on a horizontal direction, a number of folds of a first folding part of the guide part in the folded state is greater than a number of folds of a second folding part of the guide part in the folded state. 
     
     
         9 . The apparatus of  claim 7 , wherein, when an angle in a horizontal direction of the cockpit is smaller than a first reference value, a number of folds of a second folding part of the guide part in the folded state is greater than a number of folds of a first folding part of the guide part in the folded state. 
     
     
         10 . The apparatus of  claim 1 , wherein the absorber is provided integrally with the airbag door. 
     
     
         11 . The apparatus of  claim 10 , wherein the airbag door is configured to be integrally deployed with the airbag when the airbag is deployed. 
     
     
         12 . The apparatus of claim ii, further comprising a deploy part engaged with an inner surface of the airbag door, wherein a first end of the deploy part is located on both ends of the airbag door and a second end of the deploy part is fixed to and located on an inner side of the cockpit. 
     
     
         13 . The apparatus of  claim 1 , wherein the airbag comprises:
 a first airbag configured to provide a force in a deployment direction based on a housing; and   a second airbag located outside the first airbag and configured to be deployed in a width direction.   
     
     
         14 . A vehicle comprising:
 an occupant seat disposed in an interior of the vehicle;   a cockpit disposed in a front side of the interior of the vehicle;   an airbag disposed inside the cockpit;   an airbag door disposed in the cockpit at a position facing an occupant knee area provided between the cockpit and the occupant seat, the airbag door being configured to open when the airbag is deployed;   an absorber disposed at a front end of the airbag when the airbag is in a non-deployed state and when the airbag is in a deployed state; and   a guide part surrounding at least two surfaces of the absorber and the airbag when the airbag is in the non-deployed state and when the airbag is in the deployed state.   
     
     
         15 . The vehicle of  claim 14 , wherein the absorber comprises two foams located adjacent to each other and having a first spacing between the two foams when the airbag is in the non-deployed state. 
     
     
         16 . The vehicle of  claim 15 , wherein the two foams are spaced apart from each other by a second spacing larger than the first spacing when the airbag is in the deployed state. 
     
     
         17 . The vehicle of  claim 16 , wherein the airbag extends to fill the second spacing between the two foams when the airbag is in the deployed state. 
     
     
         18 . The vehicle of  claim 14 , wherein the airbag is mounted in a folded state in a same direction as an outer surface of the cockpit, and wherein the guide part is located on sides of the airbag in a folded state in a direction perpendicular to the outer surface of the cockpit. 
     
     
         19 . The vehicle of  claim 18 , wherein, when the cockpit has an angle that is greater than a first reference value based on a horizontal direction, a number of folds of a first folding part of the guide part in the folded state is greater than a number of folds of a second folding part of the guide part in the folded state. 
     
     
         20 . The vehicle of  claim 18 , wherein, when an angle in a horizontal direction of the cockpit is smaller than a first reference value, a number of folds of a second folding part of the guide part in the folded state is greater than a number of folds of a first folding part of the guide part in the folded state.
