Definitions

  • the present disclosure relates to the field of safety systems for vehicles. More specifically, the present disclosure relates to a safety system configured to prevent unintentional opening of a door of a vehicle when an impact is sustained by the door of the vehicle.
  • a door of a vehicle typically includes an outside handle configured to allow a user of the vehicle to open the door of the vehicle. Additionally, the door of the vehicle typically includes a door lock which is configured to keep the door of the vehicle closed until the user employs the outside handle to open the door of the vehicle. Between the outside handle and the door lock is a connection which is configured to transfer input from the outside handle and/or the user to the door lock, thereby allowing the door to be opened.
  • the connection between the outside handle and the door lock is typically a physical connection or an electronic connection. For physical connections, a door locking rod may extend between the outside handle and the door lock.
  • an outer panel of the door of the vehicle may be deformed, which may displace the door locking rod and trap the door locking rod between the outer panel of the door and a surrounding part within the door of the vehicle. Displacing and trapping the door locking rod may cause unintentional opening of the door, thereby creating an unsafe condition.
  • Many vehicles may include a rotating counterweight attached to the door locking rod which is configured to prevent the outside handle from self-opening the door when an impact is sustained by the door of a vehicle.
  • a rotating counterweight attached to the door locking rod which is configured to prevent the outside handle from self-opening the door when an impact is sustained by the door of a vehicle.
  • the counterweight may not always function as expected.
  • the door locking rod may still be trapped between the outer panel of the door and a surrounding part, causing unintentional opening of the door when an impact is sustained by the door.
  • German Patent Application No. DE102008011754 may include installing a heavy, metal part which is attached to the outer panel of the door of the vehicle and configured to only protect the outside handle when an impact is sustained by a door of a vehicle. Protecting only the outside handle does not effectively prevent the door locking rod from being trapped when an impact is sustained by the door of the vehicle. Additionally, using separate, heavy parts increases the weight and manufacturing costs associated with implementing the safety system.
  • a spacer for a door locking system of a door of a vehicle includes a handle, a handle frame, and a door locking rod
  • the spacer comprises a body having a first end and a second end, the body is configured to extend between the handle frame and a glass lower frame arranged within the door of the vehicle, and wherein, the second end of the body is capable of contacting the glass lower frame to maintain spacing between the handle frame and the glass lower frame when an impact is sustained by the door.
  • the body of the spacer is configured to extend directly from the handle frame of the door locking system.
  • the body of the spacer is configured to be integral to the handle frame of the door locking system.
  • the spacer is configured to overlap with the glass lower frame.
  • a safety system for a door of a vehicle includes an outer panel, an inner panel, and a glass lower frame configured to hold glass between the outer panel and the inner panel
  • the safety system comprises a handle configured to allow a user to open the door of the vehicle, a handle frame configured to support the handle, at least a portion of the handle frame is arranged between the outer panel and inner panel of the door of the vehicle, a door lock configured to transition between a first position and a second position, a door locking rod configured to transition the door lock between the first position and the second position, the spacer according to any aspect described herein, and wherein, the spacer is capable of contacting the glass lower frame to maintain spacing between the outer panel of the door and the glass lower frame when an impact is sustained by the door.
  • the spacer is distanced from the outer panel of the door by the handle frame.
  • the safety system and the spacer provide a lightweight, cost-efficient safety system configured to prevent a door locking rod of a door locking system from being trapped between an outer panel of a door of a vehicle and a surrounding part within the door of the vehicle, in order to prevent unintentional opening of the door of the vehicle when an impact is sustained by the door of the vehicle.
  • FIG. 10 An embodiment of a safety (spacing) system and an outside handle spacer (referred to herein as a "spacer") according to aspects of the disclosure will now be described with reference to Figures 1-6 .
  • Like numerals represent like parts, and the safety system and the spacer will generally be referred to by the reference numerals 10 and 20, respectively.
  • the safety system 10 and the spacer 20 are described with reference to specific examples, it should be understood that modifications and changes may be made to these examples without going beyond the general scope as defined by the claims.
  • individual characteristics of the various embodiments shown and/or mentioned herein may be combined in additional embodiments. Consequently, the description and the drawings should be considered in a sense that is illustrative rather than restrictive.
  • first the terms “first,” “second,” etc. may be used herein to describe various elements, components, regions, layers, sections, and/or parameters, these elements, components, regions, layers, sections, and/or parameters should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section from another region, layer, or section. Thus, a first element, component, region, layer, or section discussed herein could be termed a second element, component, region, layer, or section without departing from the teachings of the present disclosure.

  • Deformation of the outer panel 102 may cause the outer panel 102 to move closer to the glass lower frame 115 and thus displace the door locking rod 180 and/or trap the door locking rod 180 against the glass lower frame 115.
  • Displacement of the door locking rod 180 and trapping the door locking rod 180 against the glass lower frame 115 may cause the door lock 160 to transition to the unlocked state and be maintained in the unlocked state, unintentionally moving the door 100 to the open condition.
  • the spacer 20, and thus the safety system 10 is configured to prevent the door locking rod 180 from being trapped between the glass lower frame 115 and the outer panel 102 of the door 100.
  • the spacer 20 is configured to contact the glass lower frame 115 when the outer panel 102 of the door 100 is deformed, as the handle frame 140 and the spacer 20 and/or the outer panel 102 of the door 100 move closer to the glass lower frame 115 when an impact is sustained by the door 100.
  • contact between the spacer 20 and the glass lower frame 115 maintains spacing and/or a distance between the outer panel 102 of the door 100 and the glass lower frame 115 when an impact is sustained by the door 100.
  • the spacer 20 may be configured to transfer the force exerted and/or the load acting on the outer panel 102 of the door 100 to the glass lower frame 115 to deform the glass lower frame 115 when an impact is sustained by the door 100.
  • the spacer 20 contacts the glass lower frame 115 and may deform the glass lower frame 115 due to and/or with the impact sustained by the door 100 (the force exerted and/or the load acting on the outer panel 102 of the door 100 in the direction from the spacer 20 to the glass lower frame 115). It is contemplated that deforming the glass lower frame 115 also maintain spacing and/or a distance between the outer panel 102 and the glass lower frame 115. Maintaining spacing and/or a distance between the outer panel 102 of the door 100 and the glass lower frame 115 ensures that the door locking rod 180 is not trapped between the outer panel 102 and the glass lower frame 115.
  • the door locking rod 180 is free to move between the outer panel 102 and the glass lower frame 115 when an impact is sustained by the door 100. In this manner, the door lock 160 is prevented from being maintained in the unlocked state, as the door locking rod 180 can no longer be trapped between the glass lower frame 115 and the outer panel 102 when an impact is sustained by the door 100, thereby preventing the door 100 from unintentionally moving to the open condition.
