GM has filed a patent application for a dynamically adjustable box design for a pickup truck.
The GM patent filing has been assigned application number US 2023/0024934 A1 with the United States Patent and Trademark Office (USPTO) and was published on January 26th, 2023. The patent was originally filed on July 26th, 2021, and lists Anthony Bernal from Farmington Hill, Michigan, and Orlando Espana from Windsor, Canada as the inventors.
The patent describes a vehicle composed of a chassis, a passenger compartment supported by the chassis, and a box supported by the chassis and located away from the passenger compartment. Critically, the box includes a lower bed section that’s fixed to the chassis, as well as an upped bed section and a tailgate that’s connected pivotally to the upper bed section. The upper bed section and the tail gate are both “shiftable relative to the lower bed.”
The way in which the GM length-extending pickup truck box shifts relative to the lower box section is rather complicated, but appears to incorporate a series of rollers and belts to make the bed either longer or shorter, as desired.
As the patent description describes, a dynamically adjustable box section allows more flexibility for the user, as the situation warrants. While a longer box allows a user to transport bigger objects, such as lumbar or plywood, it can increase the vehicle’s overall turning radius and make parking more difficult. On the flip side, shorter boxes make a vehicle easier to drive and easier to park, but limit the user in terms of carrying capacity. Of course, pickup truck buyers typically must weigh the benefits and drawbacks of both configurations, but with this GM length-extending patent, perhaps no such compromise is necessary.
In related news, a GM patent was published in November of last year detailing a design for a pickup truck cargo bed utility wall system for easy installation of items like cargo tie-downs or accessory storage.
