Patent number: 10791801Abstract: An independent buckle release assist device that is a shaped lever that allows a user to gain mechanical advantage to release a typical seat belt release button. The device uses the seat restraint as a leverage point to create the mechanical advantage required to reduce the force of actuating the button. The release assist device is also designed to both stay mounted at least partially around the seat restraint and to be removably mounted to the seat restraint.Type: GrantFiled: May 9, 2016Date of Patent: October 6, 2020Assignee: CSL Solutions, LLCInventors: Clifford E.

Patent number: 10292877Abstract: A patient transport apparatus for moving a patient from one location to another. The patient transport apparatus comprises a suspension system to limit discomfort to the patient when the patient transport apparatus moves over disturbances in floor surfaces. The suspension system comprises suspension devices such as a spring and/or a damper. The suspension system is operable in an energy-absorbing mode in which the suspension system absorbs energy as wheels move over the disturbances during transport or a lockout mode in which the suspension system is relatively more rigid as compared to the energy-absorbing mode. A control system operates to place the suspension system in one of the modes.Type: GrantFiled: September 6, 2016Date of Patent: May 21, 2019Assignee: STRYKER CORPORATIONInventors: Jerald A. Trepanier, Kevin M. Patmore, Anish Paul, William D. Childs, Kurosh Nahavandi, Clifford E. Lambarth

Patent number: 8307473Abstract: A patient transfer device including a retractable wheel assembly, a caster brake and a track extension is provided. The retractable wheel assembly can include a cammed linkage arm operatively coupled to a retractable wheel. As the patient transfer device moves downwardly over a step, the cammed linkage arm can bear against the step, rotating the retractable wheel to a stowed position. The caster brake and the track extension can cooperate to stabilize the patient transfer device at the top and bottom of a stairway, respectively. The caster brake and the track extension can each include a high-friction engagement surface that is vertically offset from the respective caster and track. The retractable wheel assembly, caster brake and track extension can improve the control the patient transfer device along level, ramped and stepped surfaces, particularly for operators lacking sufficient training or experience.Type: GrantFiled: September 21, 2011Date of Patent: November 13, 2012Assignee: Stryker CoroprationInventors: Clifford E.
