Guidenhauser was the manufacturing company responsible for the flight harnesses used by Resistance pilots approximately three decades following the Battle of Endor. Additionally, they manufactured starfighter ejector seats that were integrated into both the UT-60D U-wing starfighter/support craft and the T-65B X-wing starfighter.
The company Guidenhauser initially appeared in The Star Wars Sourcebook, a Star Wars Legends reference book authored by Bill Slavicsek and [Curtis Smith], and published in 1987. Its status as canon was established later in Star Wars: The Force Awakens: The Visual Dictionary, a reference book released in 2015 and written by Pablo Hidalgo.
