Description

Vehicle seat with a deformation section The proposed solution relates to vehicle seats. Vehicle seats are generally adjustable to provide comfortable seating positions for various seat users and to adapt to various spatial conditions. To give just a few examples, a vehicle seat may be mounted in a vehicle so that it can be adjusted longitudinally by a longitudinal adjustment mechanism to provide various seating positions along the longitudinal vehicle axis, the seat may be adjustable by a height adjustment mechanism to set the seat height, and the tilt of the backrest may be adjusted relative to the seat portion. Particularly for passengers, and in the case of autonomous vehicles to provide a comfortable seating position for the driver while driving, the vehicle seat may be designed to transition to a relaxed position where the seat portion and backrest are tilted as far back as possible. However, in this position of the vehicle seat, significant force will be applied to the spine during a frontal collision due to the restraint of the user's pelvis. As a result, the risk of injury to the user may increase depending on the specific configuration of the vehicle seat. DE 10 2022 004 499 A1 describes a solution to this problem that can reduce the load on the spine by blocking the seat user. However, this solution is expensive to manufacture and requires a relatively large space. FIG. 1 shows a vehicle seat having a support mechanism for setting the vehicle seat to a relaxed position and a more upright position compared to this position, where the vehicle seat is shown in an upright position. Figure 2 shows the vehicle seat shown in Figure 1 in a relaxed position. Figure 3 shows that the vehicle seat shown in Figure 1 is in a safe position after deformation of the deformation section. Figures 4a and 4b respectively show the vehicle seat shown in Figure 1 in an upright position and another safe position after deformation of the deformation section. Figures 4c and 4d show enlarged views of the deformation section shown in Figures 4a and 4b, respectively. FIG. 4e shows one embodiment of the modified section. Figure 5 shows the vehicle seat shown in Figure 1 in a relaxed position, where the additional airbag is shown in a non-deployed state. Figure 6 shows the vehicle seat shown in Figure 5 in a safe position, where the airbag is shown in a deployed state. FIG. 7 is a partial cutaway view showing the vehicle seat shown in FIG. 1 in the relaxed position, and the locking device of the first arm of the support mechanism in the locked position. Figure 8 shows the vehicle seat shown in Figure 7, where the locking device is shown in the unlocked position. Figure 9 shows an enlarged view of the locking device of Figure 8. FIGS. 10a-10d show various possible embodiments of the first arm of the support mechanism of the vehicle seat shown in FIG. 1. Figures 11a and 11b show a modified section having a bolt. Figure 12 shows several possible variation sections. FIG. 1 shows a vehicle seat (1) including a seat portion (10) and a backrest (11). The backrest (11) is pivotally mounted to the seat portion (10) around a pivot axis (S1) via a mounting device. The vehicle seat (1) also includes a base (12) and a support mechanism (13). In this example, the base (12) includes a longitudinal adjustment device having two floor rails (122), and in the side view shown in FIG. 1, the left floor rail (122) can be seen from the perspective of a user (2) sitting in the vehicle seat (1). The corresponding right floor rail (122) is formed similarly to the left floor rail (122) (e.g., identically or mirror-symmetrically). This is also true for other components of the base (12) and the support mechanism (13) as described below. The floor rail (122) can be mounted on the floor of the vehicle and, when mounted, is attached to the floor of the vehicle. Each seat rail (121) is coupled to each floor rail (122) so as to be movable in the longitudinal direction. A holder (120) is attached to each seat rail (121). Thus, the vehicle seat (1) can be set to various positions along the longitudinal extension of the floor rail (122). At this time, it should be noted in advance that the vehicle seat (1) can also be formed without a longitudinal adjustment device. For example, the holder (120) can be attached directly to the floor of the vehicle, or the floor of the vehicle itself can serve as a base and may include a bearing point for mounting a support mechanism (13). Through the support mechanism (13), the seat portion (10) and the backrest (11) are supported on the base (12) in a rear area (B1) adjacent to the backrest (11) and in a front area (B2) further away from the backrest (11). The support mechanism (13) has a first arm (130A) and a second arm (131) in the front area (B2) (on each side), and through these arms, the seat portion (10) and the backrest (11) are supported on the base (12). Additionally, the support mechanism (13) has a rear arm (134) in th
