Patent number: 11959954Abstract: A microstrip to waveguide transition comprising a waveguide module and a section of printed circuit board (PCB). The waveguide module comprises a waveguide aperture and a repetitive structure, the waveguide aperture being arranged extending through the module for attaching a waveguide to an external side of the module, the repetitive structure comprising a plurality of protruding elements arranged to surround the waveguide aperture on an internal side of the module and to define a passage into the waveguide aperture on the internal side, wherein the repetitive structure is configured to attenuate electromagnetic signal propagation in a frequency band past the repetitive structure while allowing propagation via the passage, the transition further comprising a PCB with a patch antenna connected to a transmission line and arranged to face the passage into the waveguide aperture.Type: GrantFiled: September 19, 2019Date of Patent: April 16, 2024Assignee: GAPWAVES ABInventors: Hanna Karlsson, Esperanza Alfonso Alós, Magnus Gustafsson, Thomas Emanuelsson

Patent number: 11351950Abstract: A vehicle seat for supporting an occupant in a sitting position includes a backrest, and an airbag unit. The airbag unit comprises an inflatable airbag provided in an initially rolled and/or folded airbag package, and an inflator actuable to direct inflating gas into the airbag to inflate the airbag into an inflated configuration. The airbag comprises a pair of inflatable chambers which are physically connected to one another via a connecting interface, and are fluidly isolated from one another.Type: GrantFiled: March 4, 2019Date of Patent: June 7, 2022Assignee: Autoliv Development ABInventors: Par Sandinge, Mikaela Hagg, Hanna Karlsson, Malin Leijer, Mats Berntsson, Kevin Wikstedt, Fredrik Kjell, Carl-Johan Svensson, Jules Houessou, Ola Henriksson

Patent number: 11338757Abstract: There is proposed a vehicle seat configured to support an occupant (401) in a sitting position, the seat comprising: a squab (27), a backrest (28), and an airbag unit. The airbag unit comprises an inflatable bag (1) and an inflator (34). The airbag comprises an inflatable chamber (8, 9; 208). The airbag further comprises an inflatable guide (2), connected to the inflator and the inflatable chamber. Upon actuation of said inflator, said inflatable guide is at least partially inflated before the inflatable chamber, thereby initially urging the inflatable chamber away from the backrest of the seat. The airbag is configured such that after the inflatable guide is at least partially inflated, the inflatable chamber inflates into a deployed position in which it defines an inflated shroud which extends over said sitting position and provides lateral protection to said occupant of the seat in said sitting position.Type: GrantFiled: June 13, 2019Date of Patent: May 24, 2022Assignee: Autoliv Development ABInventors: Mikaela Hagg, Malin Leijer, Mats Berntsson, Kevin Wikstedt, Par Sandinge, Fredrik Kjell, Jules Houessou, Carl-Johan Svensson, Hanna Karlsson, Ola Henriksson
