First Claim
1. A curtain airbag cushion, provided at a position adjacent to a roof panel of a vehicle by a cushion holder, the curtain airbag cushion being deployed downwards to protect a passenger by explosion of an inflator, comprising:
- the inflator connected to a portion of an upper end of the cushion, wherein the curtain airbag cushion has a predetermined length such that the cushion is deployed to a position at which the cushion covers a body of the passenger when the inflator explodes; and
a blocking part formed in the cushion at a position adjacent to the inflator and extending in a predetermined length in a vertical direction to partition an interior of the cushion into a plurality of portions fluid-communicating with each other,wherein the blocking part has a lower end spaced apart from a lower end of the cushion by a predetermined distance to form a space, so that when the inflator explodes, gas is guided towards a lower portion of the cushion by the blocking part and then guided towards an upper portion or a front portion of the cushion through the space,wherein the blocking part comprises a plurality of blocking parts, one of which is adjacent to the inflator and oriented in the vertical direction and the others are oriented in the vertical direction, in a forward and rearward direction or in a diagonal direction, andwherein size of the plurality of blocking parts is sequentially reduced along an input direction of gas at the portion of the cushion connected to the inflator.

Abstract
Disclosed herein is a curtain airbag cushion. The cushion has a length appropriate for being deployed to the chest of a passenger. A blocking part which partitions the interior of the cushion into portions is oriented in the vertical direction. The lower end of the blocking part is spaced apart from the bottom of the cushion by a predetermined distance. Thus, when an inflator explodes, gas discharged from the inflator is guided towards the lower portion of the cushion and then guided towards the front or upper portion of the cushion through the space between the lower end of the blocking part and the bottom of the cushion.
