Patent number: 8414022Abstract: A passenger airbag system includes an airbag cushion with an upper airbag chamber and a lower airbag chamber. The front face of the lower airbag chamber has an upper edge joined to the lower face of the upper airbag chamber at a connection region. An upper airbag chamber length is defined as a horizontal distance between the portion of the front face of the upper airbag chamber closest to the passenger and the portion of the mid portion of the instrument panel closest to the passenger. A lower airbag chamber front offset is defined as a horizontal distance between the portion of the front face of the upper airbag chamber closest to the passenger and the connection region. The lower airbag chamber front offset is at least 25% of the upper airbag chamber length.Type: GrantFiled: December 10, 2010Date of Patent: April 9, 2013Assignee: CIS Tech, LLCInventors: Seung-Jae Song, Jong Seop Nam

Patent number: 7731229Abstract: A passenger airbag system is designed for an automotive vehicle with a passenger compartment, a windshield and an instrument panel disposed between the passenger compartment and the windshield. The instrument panel has a top portion adjacent the windshield, a lower surface generally directed toward the legs of an occupant and a mid-portion with a surface that extends between the top and lower portions. The system includes a first airbag and a second airbag both disposed in the instrument panel. Each airbag has a cushion deployable from the housing through the instrument panel along a predetermined path for direct contact with an occupant seated in the passenger compartment. The second airbag has a lower portion when deployed that fills a space between the occupant's lower extremities and the lower portion of the instrument panel and thus acts as a knee airbag.Type: GrantFiled: May 15, 2007Date of Patent: June 8, 2010Assignee: CIS Tech, LLCInventors: Seung-Jae Song, Jong Seop Nam

Patent number: 7686326Abstract: Disclosed herein is a low risk deployment passenger airbag system using a slim type passenger airbag module which is minimized in height and/or length, such that a top airbag and a mid airbag can be installed in a limited space defined by an instrument panel. In the slim type passenger airbag module used in the low risk deployment passenger airbag system, a disk type inflator is used, unlike the conventional art using a cylindrical inflator, an upper end of the disk inflator is disposed in an airbag housing, and a retainer for supporting the cushion is brought into close contact with the bottom (or the rear surface) of the airbag housing in which the disk type inflator is provided, thus minimizing the height and/or length of the passenger airbag module. Thereby, the slim type passenger airbag module is suitable for the low risk deployment passenger airbag system.Type: GrantFiled: October 30, 2008Date of Patent: March 30, 2010Assignees: S&T Daewoo Co. Ltd., CIS Teck, LLCInventors: Dong Eun Kim, Young Yeol Park, Jong Seop Nam, Seung Jae Song

Publication number: 20090200774Abstract: A side head airbag is installed in a headrest of a vehicle seat and deploys laterally forward with respect to the vehicle toward a gap located between an occupant's head and a side window for the protection of the occupant's head during a serious side impact crash. The side head airbag has a tether constructed in such a way as to minimize the inefficient voids that are commonly seen from side curtain airbags. The side head airbag may have a two chamber construction to improve the energy absorption mechanism from an elastic loading/unloading to a plastic loading/unloading along with a roll-over protection. Another restraint may be installed, separately from the head airbag, in a seatback or in a side structure to protect an occupant's thorax and/or pelvis during a serious side impact crash.Type: ApplicationFiled: April 14, 2008Publication date: August 13, 2009Applicant: CIS Tech, LLCInventors: Jong Seop Nam, Seung-Jae Song

Publication number: 20090160171Abstract: A driver airbag includes a front panel facing a driver and an opposite rear panel. Each panel has a central region and a perimeter with a center point being defined at the geometric center of the panel. The perimeters of the front and rear panels are joined to provide an airbag outer shell. A lower tether has a first end secured to the central region of the front panel and a second end being secured to the central region of the rear panel. An upper tether or membrane has a perimeter that is secured to the front and rear panels above the center points thereof. A lower chamber is defined by and below the upper tether and an upper chamber is defined by and above the upper tether. The upper tether has an opening defined therethru for gas to flow from the lower chamber to the upper chamber.Type: ApplicationFiled: March 21, 2008Publication date: June 25, 2009Applicant: CIS Tech, LLCInventors: Jong Seop Nam, Seung-Jae Song

Patent number: 7328913Abstract: A passenger airbag system is designed for an automotive vehicle with a passenger compartment, a windshield and an instrument panel disposed between the passenger compartment and the windshield. The instrument panel has a top portion with a surface which is more horizontal than vertical and generally directed toward the windshield and a mid-portion with a surface that is more vertical than horizontal and generally directed toward an occupant of the passenger compartment. The system includes a single airbag housing that is disposed in the instrument panel and extends from the top portion to the mid-portion. The airbag cushion is deployable from the housing through the instrument panel along a predetermined path for direct contact with an occupant seated in the passenger compartment. The predetermined path is generally radial with respect to the surface of the instrument panel.Type: GrantFiled: November 1, 2005Date of Patent: February 12, 2008Assignee: CIS Tech, LLCInventors: Seung-Jae Song, Miyoung Jang, Jong Seop Nam
