The control system comprises at least one sensor and at least one actuator. The sensor includes: at least one actuating element actuatable to generate a control signal; an interface to emit the control signal; and a fastening element by which the sensor is attachable to the head, foot, or side part of the bed without a tool. The actuator includes: an interface to receive the control signal; and a switching element to switch at least one current path or an adjusting element to set at least one voltage, one current, or another physical variable based on the control signal. ## Claims ### Claim 1 A bed, comprising: a height-adjustable lying surface, upon which a mattress rests; a head part, a foot part, and/or at least one side part, wherein at least one of the parts in at least one state of the bed projects beyond the mattress of the bed; a motor to adjust the height of the lying surface as a mechanism for assisting standing up; a control system to control the motor to adjust the height, wherein the control system comprises: at least one sensor including: at least one actuating element that can be actuated to generate a control signal; an interface to emit the control signal; and at least one fastening element by which the sensor can be attached to the head part, the foot part, and/or the side part of the bed, wherein the head part, the foot part and/or the side part comprise support structure on which the sensor can be mounted without a tool by interaction with the at least one fastening element; and at least one actuator including: an interface to receive the control signal; and a switching element to switch at least one current path or an adjusting element to set at least one voltage, one current or another physical variable on the basis of the control signal; and a handle as a mechanism for assisting standing up, wherein the handle and the sensor are parts of a handle-sensor unit of the bed. ### Claim 2 (depends on 1) The bed of claim 1, wherein the interface of the sensor and the interface of the actuator are radio interfaces. ### Claim 3 (depends on 2) The bed of claim 2, wherein the sensor comprises at least one element to produce energy, by which energy needed to generate and transmit the control signal can be generated via actuation of the sensor from the outside. ### Claim 4 (depends on 3) The bed of claim 3, wherein the at least one element to produce energy is a piezo element or an electrodynamic energy converter. ### Claim 5 (depends on 4) The bed of claim 4, wherein the actuating element is configured for mechanical actuation and is operatively connected to the piezo element or to the electrodynamic energy converter. ### Claim 6 (depends on 5) The bed of claim 5, wherein the actuating element can be actuated by a rocker and/or a key or forms a rocker or a key. ### Claim 7 (depends on 1) The bed of claim 1, further comprising at least one further motor to adjust the inclination of the lying surface or a part of the lying surface. ### Claim 8 (depends on 1) The bed of claim 1, wherein the sensor comprises one or more fastening elements which form a receptacle with undercut edges. ### Claim 9 (depends on 8) The bed of claim 8, wherein, in one direction, the receptacle has a clear cross section which is uniform at least in sections. ### Claim 10 (depends on 8) The bed of claim 8, wherein the receptacle is configured to be plugged, clipped, or pushed onto the support structure and the support structure is designed to be complementary to the receptacle. ### Claim 11 (depends on 1) The bed of claim 1, wherein the handle comprises a foot comprising the fastening element or elements, and a head rotatably connected to the foot. ### Claim 12 (depends on 1) The bed of claim 1, wherein the at least one actuating element is provided in or on the head. ### Claim 13 (depends on 1) The bed of claim 1, wherein the head substantially has a spherical shape or a barrel shape. ### Claim 14 (depends on 1) The bed of claim 1, wherein the bed is a hospital bed or a nursing care bed.
