Abstract: A tether arrangement for connecting an electronic device, such as a laptop computer, to a person who is using the device, on the lap, while in a seated position. In one embodiment, a flexible cord with two ends connects on one of its ends to the electronic device and on the other of its ends to the belt loop of the user. In another embodiment, a single long tethering cord extends around the back of the user, with both ends being connected to the electronic device. Tethers may connect to the electronic device by permanent attachment, by connection terminals on the device, by elements that encircle a portion of the device, or by other means. Tethers may connect to users by clips or by other means. Tethers may also be rigid or semi-rigid, such as plastic strips or rods. Two or more tethers may be used together. Means for varying the effective length of the tethers may be present. These tether arrangements provide for multiple functions, including helping prevent the electronic device from falling off the lap.
