Knee airbag for vehicles

A knee airbag for vehicles disposed in a region facing an occupant's knees in a cockpit module, the knee airbag comprising:

• a main panel configured to be deployed toward the occupant;
• and
• a partition unit disposed inside the main panel and configured to partition an inner space of the main panel into a protection region and a non-protection region, and to form a bypass flow path inside the main panel so that the protection region is deployed later than the non-protection region,
• wherein the main panel includes:
• a non-contact portion configured to face the cockpit module when the knee airbag is deployed;
• a contact portion configured to face the occupant when the knee airbag is deployed;
• a first connection portion disposed between and separating the non-contact portion and the contact portion;
• and
• a second connection portion connected to the contact portion and configured to be folded over and connected to the non-contact portion,
• wherein the partition unit includes:
• a branch plate disposed proximate to the second connection portion;
• and
• side plates disposed at both ends of the branch plate, the side plates each being spaced apart from respective edge regions of the main panel to form branches of the bypass flow path along each of the side plates,
• wherein the branch plate is configured to direct gas entering the main panel toward each of the branches of the bypass flow path.
